Sealed Fedora Atomic Desktop bootable container images

Siosm’s blog — Mon, 27 Apr 2026 22:00:00 +0000

I’m happy to announce that we have sealed bootable container images ready for testing for the Fedora Atomic Desktops!

Note: You can also read this post on the Fedora Magazine.

What are sealed bootable container images?

Sealed bootable container images include all the components needed to create a fully verified boot chain, from the firmware to the operating system composefs image. This relies on Secure Boot and thus only supports system booting with UEFI on x86_64 & aarch64.

The components are:

systemd-boot as bootloader,
a Unified Kernel Image (UKI) which includes the Linux kernel, an initrd and the kernel command line,
a composefs repository with fs-verity enabled. This is managed by bootc.

Both systemd-boot and the UKI are signed for Secure Boot. The images are test images so the components are not signed with the official keys from Fedora.

The main direct benefit that we will get from this support is that we will be able to enable passwordless disk unlocking using the TPM in a way that will be reasonably secure by default.

How do I test those images?

See the instructions at github.com/travier/fedora-atomic-desktops-sealed on how to give the pre-built container and disk images a try and how to build your own.

We welcome testing and feedback! Please see the list of known issues and report new issue at github.com/travier/fedora-atomic-desktops-sealed. We’ll redirect them as needed to the right upstream projects.

Beware, those are testing images. The root account does not have a password set and sshd is enabled, by default, to make debugging easier. The UKI and systemd-boot are signed for Secure Boot but, since those are test images, they are not signed with the official keys from Fedora. Don’t use those images in production.

Where can I get more details about how this work?

If you want to know more about how sealed images work (i.e. how we make bootable containers, UKI and composefs work together to create a verified boot chain), see the following presentations and documentation:

Thanks to all the contributors that made this possible, notably (but non exhaustively) from the following projects: bootc & bcvk, composefs & composefs-rs, chunkah, podman & buildah and systemd.

What’s new for Fedora Atomic Desktops in Fedora 44

Siosm’s blog — Mon, 27 Apr 2026 22:00:00 +0000

Fedora 44 has been released! 🎉 So let’s see what is included in this new release for the Fedora Atomic Desktops variants (Silverblue, Kinoite, Sway Atomic, Budgie Atomic and COSMIC Atomic).

Note: You can also read this post on the Fedora Magazine.

Changes for all Atomic Desktops

Issue tracker moved to the new Fedora forge

We have moved the cross-variants issue tracker to the new Fedora forge. This is the best place to file issues that impacts all variants or to coordinate work between all of them. If you have issues specific to a given desktop environment then we usually prefer to track them in each respective SIG trackers. They are listed on the README for the atomic-desktops organization.

Unified documentation, hosted on the new forge

The unified documentation for all Atomic Desktops is finally live! Unfortunately the translations have not been migrated so we will need help to re-translate everything again, once the translation setup is ready with the new forge. It should be mostly copy/paste from the previous docs and this time we will only have to translate the docs once and not for every (new) variant.

See the tracking issue atomic-desktops#10.

Removal of FUSE version 2 libraries

FUSE version 2 has been deprecated and unmaintained for a while so we have removed it from the images. In practice, this means two things:

If you are using AppImages, some of them may not work anymore.
If you are using legacy backends with Plasma Vault on Kinoite, you need to migrate your data.

See the Fedora Change and the tracking issue atomic-desktops#50.

The implications are detailed below.

AppImages and the FUSE 2 libraries

Some AppImages are still using an old AppImage runtime that relies on FUSE 2 libraries being available on the host. See the discussion thread for examples on how to check the runtime of an AppImage.

If some of your AppImages do not work on Fedora Atomic Desktops 44, we recommend:

Looking for a Flatpak for the application and giving it another try. Consider helping upstream package their application as a Flatpak.
Reporting the issue upstream so that they are aware that they should use a newer runtime. Consider helping upstream with this as well.

EncFS or CryFS backends for Plasma Vaults are removed

KDE upstream no longer recommend using the EncFS nor CryFS backends for Plasma Vaults, notably because they rely on the FUSE 2 libraries. If you are using one of those backends, you should migrate your data to a new Vault using the only maintained backend (gocryptfs). Ideally this should occur before the update to Fedora 44. If you have already updated to Fedora 44 and need access to your data, you can layer the needed packages (cryfs or fuse-encfs) using rpm-ostree install <package>, then migrate your data and finally reset the layers with rpm-ostree reset.

Dropping compatibility for pkla polkit rules

Support for the legacy pkla polkit rules format has been removed. It is unlikely that you were relying on support for those rules as most of the ecosystem has moved on to the new Javascript based format.

See the Fedora Change and the tracking issue atomic-desktops#102.

What’s new in Silverblue

GNOME 50

Fedora Silverblue comes with the latest GNOME 50 release.

For more details about the changes that alongside GNOME 50, see What’s new in Fedora Workstation 44 on the Fedora Magazine.

What’s new in Kinoite

KDE Plasma 6.6

Fedora Kinoite ships with Plasma 6.6, Frameworks 6.24 and Gear 25.12.

See also What’s new in Fedora KDE Plasma Desktop 44 on the Fedora Magazine.

The brand new Plasma Login Manager replaces SDDM to provide a more integrated experience with systemd and the KDE Plasma session.

See the Fedora Change.

Unified out of the box experience with KDE Plasma Setup (OEM installation)

Thanks to the new Plasma Setup, it is now possible to install the system with Anaconda with minimal configuration and then complete the installation on the first boot by creating a new user and selecting the timezone. This is great when you want to install Fedora Kinoite on a computer and don’t want to setup a user in advance.

See the Fedora Change.

What’s new in Sway Atomic

Nothing specific for this release.

What’s new in Budgie Atomic

Fedora Budgie Atomic comes with the latest 10.10.2 Budgie release. This release brings Wayland support to Budgie Atomic. See the 10.10 release announcement for more details.

What’s new in COSMIC Atomic

Fedora COSMIC Atomic comes with the latest 1.0.8 release of the COSMIC desktop. This is now considered stable.

Universal Blue, Bluefin, Bazzite and Aurora

Our friends in the Universal Blue project (Bazzite, Bluefin, Aurora) have prepared the update to Fedora 44. Look for upcoming announcements in their Discourse.

As always, I heavily recommend checking them out, especially if you feel like some things are missing from the Fedora Atomic Desktops and you depend on them (NVIDIA drivers, extra media codec, out of tree kernel drivers, etc.).

What’s next

Helping us with a few nasty bugs

If you are interested in contributing to Fedora Atomic Desktops, here are some bugs that we will have to fix in the short term. We would greatly appreciate help with:

Fixing root mount options (atomic-desktops#72): This is a long standing and mostly invisible bug that impacts performance.
Moving away from nss-altfiles (atomic-desktops#108): This is another long standing source of issues that new users regularly face.

Sealed Fedora Atomic Desktop bootable container images

Sealed images are now ready for testing! See the other article for all the details.

Roadmap to Bootable Containers

A lot of work is happening to make the transition to Bootable Containers as smooth as possible for our existing users. You can look at the roadmap for this transition at atomic-desktops#26.

One of the tasks is to move away from our unmaintained installation ISO building scripts to the new image-builder tooling. This is planned for Fedora 45 for the ostree variants and support for Bootable Container will follow right after.

Another task is to start building the Fedora Atomic Desktops Bootable Container images using the Fedora Konflux instance.

We are looking for contributors to help us make the Fedora Atomic Desktops the best experience for Fedora users.

Announcing Sigrún (Run a command)

Andreas Schneider — Mon, 27 Apr 2026 12:15:56 +0000

Some time ago I used a feature in KDE called “Run a command” when an event triggered. It triggered for me when a calendar event fired and used Piper TTS to read the event to me out loud. A small popup and a pling don’t work for me.

I tried to get the feature back into KDE, but since the merge request isn’t going anywhere and people don’t give details how to implement it correctly I wrote Sigrun now. It is named after a Norse Valkyrie and is short for Signal Run.

It is a systemd service running as a user and listening on DBus signals. Once it finds a configured one, it runs its command. The desktop doesn’t matter.

Here is the rule that reads my calendar reminders aloud via kde-tts.py:

[[rule]]
name = "calendar-tts"
[rule.event]
type = "notification"
[rule.filter]
app_name = "kalendarac"
summary = "Meeting.*"
[rule.filter.hints]
"x-kde-eventId" = "reminder"
[rule.action]
command = "/usr/local/bin/kde-tts.py"
args = ["-t", "{summary}", "-d", "{body}"]

Kdenlive 26.04.0 released

Kdenlive — Mon, 27 Apr 2026 11:30:00 +0000

The Kdenlive team is happy to announce the first major release of 2026. This cycle focuses on stability, interface polish and usability improvements.

For the first time in Kdenlive's history, this version includes features implemented by so many different contributors. Our developer community is growing, don't hesitate to join us building a free and open source video editing program that respects the users privacy and provides a tool to democratize communication.

In case you missed it, check out the State of Kdenlive to learn more about the project's health and the nifty features coming soon.

Monitor Mirroring

This feature allows you to mirror any monitor while working in fullscreen mode. It’s especially useful when working with multiple displays or collaborating with others in the editing room, making it easier to share what you're doing without disrupting your workspace.

Effects and Transitions

This release improves effect and transition workflow. We improved the logic for luma files to adapt to different project profiles and automatically reload previews of downloaded lumas. We added a dedicated tab in the transitions list to browse luma files and added the ability to drag-and-drop transitions directly onto timeline clips. This release also comes with a new Euclid Eraser transition and a Heatmap effect. We also fixed issues with audio TAP effects and improved internationalization support, fixed a bug in the Video Noise Generator effect and scaling issues in the Transform effect.

Animated Previews

Transitions now include animated previews, making it much easier to visualize how they will look before applying them. Additionally, dropping a transition onto the timeline can now automatically adjust its duration to match the clips above and below, saving time and reducing manual tweaking. The first version of this feature was originally written by Swastik Patel, during KDE's SoK 2025.

Automatic Adjustment

Transitions automatically adjust to the length of the clip they are being applied to.

Math Expressions

Added basic math expression support in effect spinboxes.

New Heatmap Effect

Added a new frei0r heatmap0r effect.

Interface and Usability Improvements

Timeline

This release comes with many usability and workflow improvements to the timeline, such as a Disable Timeline Effects function to timeline hamburger menu, the ability to import and add clips directly from the timeline context menu with a smart length detection function, and sequences now have audio thumbnails. Other highlights include:

Continuous Panning

Hold the middle mouse button and drag to continuously pan the timeline even when going outside of the screen edges. Implemented by Abdias J Moya Perez.

Fixed Playhead

Added the option to lock the playhead at the center of the timeline during playback, scrubbing or seeking. Implemented by Abdias J Moya Perez.

Playhead/Mouse Zoom

Added a button in the Status Bar to toggle between zooming to the mouse cursor position or the playhead position. Implemented by the mrfantastic.

Multi-Clip Speed Changes

Added the ability to change the playback speed of multiple clips at once either by directly ctrl + dragging in the timeline or by using the Clip Speed tool. Implemented by Vineet Tiwari.

Audio Capture

Improved support for external recording devices, now the channel count and sample rate combo boxes only display values supported by the selected hardware. Also added the option to choose the sample format (8bit, 16bit, 32bit, and float) as well as a button to use the hardware's default settings.

Subtitles and Speech Tools

This release fixes issues with cutting, moving, and saving subtitles, and solves a crash cutting subtitle clips. It also fixes a problem where searching for multiple words in the Speech Editor did not work correctly. We also improved the installation process for the Whisper and SeamlessM4T plugins and updated their requirements.

Other Noteworthy Features

Added Clear Undo History option in the Edit menu
Added HD-ready (1366×768) resolution to project profiles
Added Add to Project Bin option to Render Widget to directly add rendered file to the Project Bin
Hide mouse cursor when placed over monitor in fullscreen and not moving for 2 seconds
Added option to edit a video clip with external program (useful for programs like Gyroflow)
Rearranged Marker menu items into groups and added a Delete All Timeline Markers action
Ability to directly add clips to folders from the context menu in the Project Bin
Added AMF encoding profile for Windows

This Week in Plasma: fanciness in Discover and more power efficiency

Nate Graham — Sat, 25 Apr 2026 00:00:01 +0000

Welcome to a new issue of This Week in Plasma!

This week includes an interesting blend of improvements. Lots of visual stuff, so get ready for a ton of screenshots and screen recordings!

Notable new features

Plasma 6.7

The Kicker Application Menu widget can now be configured to show a “Recent Locations” item. (Christoph Wolk, KDE Bugzilla #420951)

Network connections can now be duplicated. (Kartikeya Tyagi, KDE Bugzilla #499188)

There’s now a new “has parent window” window rule you can use to target child dialog windows specifically. (Kai Uwe Broulik, kwin MR #8969)

Notable UI improvements

Plasma 6.6.5

Dragging a search result for a System Settings page to the desktop now creates a launcher to that page as you would expect. This completes a mini-project to improve dragging-and-dropping things to the desktop that we started a while back. (Antti Savolainen, KDE Bugzilla #500259)

Plasma 6.7

Discover now has fancier application page headers with more obvious install buttons! (Oliver Beard, discover MR #1297)

Discover no longer disables the “More Information” button on list items for in-progress updates. (Tobias Fella, KDE Bugzilla #431719)

Discover now does a better job of handling the rare case where an automatic update to a Flatpak app introduces a compatibility issue you can’t easily recover from. Now it will warn you about this once instead of continuously. (Tobias Fella, KDE Bugzilla #509760)

You can now drag favorite apps out of their areas in Kicker and Dashboard to un-favorite them. Kickoff is coming soon, too! (Christoph Wolk, plasma-desktop MR #3665 and KDE Bugzilla #518749)

When your laptop is plugged in at maximum charge, doing something that changes the power profile to a non-default one now shows only the power profile icon in the System Tray, and omits the fully-charged battery icon because that part is obvious. (Nate Graham, KDE Bugzilla #518802)

Improved some awkwardly-worded labels in System Settings and Plasma. (Philipp Kiemle, plasma-desktop MR #3674 and plasma-workspace MR #6522)

Frameworks 6.26

Reduced the amount of blurriness seen in icons throughout QtQuick-based apps using the Kirigami.Icon component when using a low fractional scale factor like 150% or less. (Volodymyr Zolotopupov, kirigami MR #2070)

Plasma 6.6.5

Fixed a case where the Plasma Login Manager could crash when connecting and disconnecting multiple monitors while the login screen is visible. (David Edmundson, KDE Bugzilla #519302)

Fixed some cases where Plasma could crash at login. (David Edmundson, plasma-workspace MR #6520)

Fixed multiple accessibility issues: key repeat not working in the Orca screen reader, and various UI elements not being read properly. (Nicolas Fella, KDE Bugzilla #519143, KDE Bugzilla #519333, and KDE Bugzilla #519217)

Fixed a tricky issue in Spectacle that could make large images fail to automatically copy to the clipboard right after the app exits. (David Edmundson, KDE Bugzilla #509065)

Fixed another cause of the issue whereby de-focused full-screen windows could sometimes inappropriately appear at the top of the window stack. (Xaver Hugl, KDE Bugzilla #484155)

Fixed a layout glitch on System Settings’ Colors page that could make UI elements in the color previews overflow when using some non-default fonts and font sizes. (Akseli Lahtinen, KDE Bugzilla #516413)

Changing the brightness or any screen settings no longer terminates Spectacle’s sectangular region recordings. (Xaver Hugl, kwin MR #9127)

Frameworks 6.26

Fixed some visual glitches around radio buttons in the Audio Volume widget. (David Edmundson, ksvg MR #103)

Notable in performance & technical

Plasma 6.6.5

Fixed an issue that made System Settings’ Touchscreen page appear while the “highlight changed settings” feature is enabled even if you don’t have a touchscreen. (Jin Liu, KDE Bugzilla #518868)

Plasma 6.7

Turned on the “overlay planes” feature for Intel GPUs, which should improve performance and save some energy when using cooperative games and apps. (Xaver Hugl, kwin MR #8699)

Improved power efficiency for full-screen windows and effects that don’t gain any benefit from using the “direct scan-out” feature; now they’ll only use it if it will save power. (Xaver Hugl, kwin MR #9120)

Automatic brightness in Plasma

Xaver’s blog — Fri, 24 Apr 2026 19:30:00 +0000

As an exception to my usual posts, this time I’ll write about a feature that’s already released. Since Plasma 6.6, you can enable automatic brightness in the display settings… let’s take a look at how it works, and why it took so long to make it happen.

The hardware

This is where the problems start - most laptops unfortunately don’t come with a brightness sensor, and there’s effectively no monitors that have a built-in sensor either (let alone one that can be accessed by the connected PC).

While it’s possible to buy or build a brightness sensor that connects via USB, brightness control for external monitors usually has limitations in how often we can safely adjust the brightness… So for quite some time, there was noone working on Plasma that had the combination of hardware, motivation and knowledge to do something about it.

Luckily, the Framework Laptop 13 comes with a brightness sensor, so on the hardware side I was all set:

The software

Making automatic brightness do something is easy, but making it work well enough that you actually want to use it is a very different story.

My first approach was to assume brightness of the display should scale linearly with environmental brightness. I tried this, and it was sort of usable, but just not good enough. There’s three problems with it:

the brightness setting sadly does not linearly control display luminance. 0% is generally not “off”, and sometimes firmware or drivers make the curve non-linear to make the brightness more “intuitive”
in order for automatic brightness to be easy to use, we can’t expect the end user to configure an equation for their system. We need to automatically detect what they’re doing, and configuring two parameters based off one brightness slider is a challenge
the best brightness curve isn’t necessarily linear. Depending on your personal preferences and how reflective your display is, you might want to keep brightness a lot higher in bright environments than in dark ones, or vice versa.

So a different approach was needed. I looked a bit at other operating systems for inspiration, and from the UX side I definitely wanted to copy Android: You use the brightness slider however you want, and the system should try to replicate what you do on its own. On the implemtation side however, I only saw claims that it uses machine learning, so that wasn’t exactly helpful.

Ultimately, what I settled on is pretty simple: We just store 6 sensor values, one per 20% brightness step. When processing sensor readings, KWin finds the matching brightness setting by linearly interpolating between the two closest sensor values.

When the user touches the brightness slider or uses the brightness shortcuts, KWin adjusts the curve so the current sensor value will result in that desired brightness setting. At first, I only made it adjust the two closest points and enforce the rest of the curve to be monotonic, but it ended up causing problems:

With this configuration, any sensor readings above 100 lux - for example, 101 - resulted in 100% brightness. To fix that, we now enforce a minimum difference of at least 1 lux or 10% between control points, so the curve above would look more like

To ensure the curve would always stay strictly monotonic and so you can have an arbitrary backlight setting at zero lux, values below zero also had to be allowed when updating the curve with those constraints.

However, I was still not done. While it now followed my preferences pretty well, it was still annoying! Especially if you sit in between a light source and the laptop, or if you sit on a train with trees around the tracks (like I recently did, traveling to and from Graz for a Plasma sprint), the brightness constantly fluctuated up and down.

To make it less annoying, I added some more adjustments on top:

some hysteresis. As long as the sensor reports ±10% of the last value, KWin should do nothing
a time delay before changes get applied. If after two seconds the sensor value is back in that 10% range, the brightness stays unchanged
a much slower animation for reducing display brightness (but not that much slower for increasing it)

This is how it was released in Plasma 6.6, and I’m pretty happy with it on both the Framework 13 and on my OnePlus 6 with Plasma mobile.

What now?

Just because I’m happy with it, doesn’t mean it’s done. If you’re using automatic brightness and it’s still annoying you for some reason, please tell me about it! If you’re really happy with it, I won’t complain about being told that either of course ;)

To fully catch up to what phones have done for years though, one feature is still missing: I’d like to adjust not just the brightness, but also the white point of the display to the environment. Unfortunately, none of my devices have a sensor for that… but since the camera module in the Framework 13 is easy to replace, I hope that changes one day!

Qt No Contextless Connect

Kai Uwe Broulik — Fri, 24 Apr 2026 13:49:04 +0000

As many long running projects, Qt too over the years has accumulated some APIs that in hindsight are deemed unsafe or sub-optimal. For example, Qt by default implicitly converts const char* to QString. While that usually only incurs a runtime overhead, maybe encoding problems, but also admittedly less cluttered code, there’s other APIs that can backfire in more subtle ways. One such API is doing a “context-less connect”.

Signals and Slots are a core principle of Qt that make it super easy to connect one object to another and keep a certain separation of concerns. The typical syntax to establish an connection is:

connect(sender, &Foo::somethingHappened, receiver, &Bar::doStuff);

This connects the signal somethingHappened in our sender of Type Foo to the member function doStuff in our receiver (context object) of type Bar. Whenever sender “emits” somethingHappened, doStuff on receiver will be called. The neat part about Qt connections is that when receiver gets destroyed, the connection is severed automatically. However, you can not just connect a signal to a member function but also use a lambda:

connect(job, &WallpaperFinder::wallpaperFound, [this](const QString &path) {
m_wallpapers << path;
});

In our hypothetical wallpaper selector when the “job” that goes looking for wallpapers found one, it emits a signal and tells us the path of the file, so we can show it to the user. Now what happens when the user closes the dialog (which then gets destroyed) before the job has finished? Well… job still emits the signal which then results in our lambda being called. And then we try to access m_wallpapers on this which is long gone. Boom!

The fix is easy: provide a “context object”, too, just like you would with pointer to member function:

connect(job, &WallpaperFinder::wallpaperFound, this, [this](const QString &path) {
m_wallpapers << path;
});

If this gets destroyed, the connection is severed, our lambda will no longer be called and all is well. The receiver object also decides what thread the slot is called, i.e. it will be called in the thread the receivers “lives in”. Context-less connections are always of DirectConnection type. Since Qt 6.7 you can actually enforce the use of a context object by defining QT_NO_CONTEXTLESS_CONNECT.

add_definitions(-DQT_NO_CONTEXTLESS_CONNECT)

It requires you think about the lifetime of your objects more and make a conscious decision about what your context object is. It also removes one thing to look out for in code review. I started adding this option to a couple KDE repositories to improve the quality of our code and I encourage you to do that, too! It probably comes to no surprise that in general, the bigger and older a repository, the higher the probability of it using non-ideal code.

What context object to use?

Of course, the situation is not always as simple as our example above. Here’s a few tips and tricks:

Look at the lambda captures. If you capture this, chances are, you want this as your context object.
If you capture a single object, perhaps you want it as your context object rather than this. If you use the sender, too, that’s fine, capture them both:
connect(job, &Job::finished, manager, [job, manager] { manager->report(job); });
When the sender gets destroyed, evidently the connection is useless and will be severed.
You can try to avoid capturing this by doing an init capture, i.e. [foo = m_foo] { ... }
Perhaps you don’t even need a lambda and can just connect to the method directly. Lambdas are so ubiquitous that you tend to forget you could just replace
connect(job, &Job::finished, [timer] { timer->start(); });
with:
connect(job, &Job::finished, timer, &QTimer::start);
At last, you may also use the sender as context object.
A context object must be a QObject, though. If you don’t have one, you’ll have to find another way. For instance, QObject::connect returns a QMetaObject::Connection object that you can store in a member variable and then disconnect when appropriate, like in your destructor.
For connections where it doesn’t really matter qApp can also be an option.

I’m a huge fan of QT_ENABLE_STRICT_MODE_UP_TO that lets you turn on most strictness features in a single shot. The biggest hurdle of rolling that out more widespread in KDE repositories is actually the Java-style iterators. Qt hates them, many use them, particularly for mutating a container, and imho they’re much more pleasing to look at than STL algorithms. If you start a new project, however, do consider setting your baseline to be as strict as it can be!

Web Review, Week 2026-17

Kevin Ottens — Fri, 24 Apr 2026 13:16:29 +0000

I’ll be vacationing a bit, so there will be no web review next week. It means the next one might be a double issue though, we’ll see.

Anyway, let’s go for my web review for the week 2026-17.

What Async Promised and What it Delivered

Tags: tech, asynchronous, complexity

Interesting piece which gives some perspective on the path which led to async/await. It seems to omit some pieces of the history to me but that’s a minor issue. I like how it points that it indeed led to gradual improvements locally for developers writing their functions, but is overall leading to larger issues in the involved ecosystems.

Box to save memory

Tags: tech, rust, memory

Indeed, the memory layout of your structs can matter. Be it Rust or not, but in the case of Rust the use of Option might give the wrong feel about the resulting layout.

“What’s In It For Me” Architecture

Tags: tech, architecture, organisation

Indeed, architecture work is not only technical (what is really?). You definitely need to account for the organisation and the process to actually put the architecture in place. It’s not just about having pretty pictures.

Good architecture shouldn’t need a carrot or a stick

Tags: tech, architecture, organisation

Architecture work is not only technical, you need processes to put the architecture of a project in place. That said, you can make things easier with standards to smooth the path toward the preferred types of architectures in your organisation.

Speaking at Chennai FOSS: GUI Design, QT, SOK and a lot more

Sayandeep Dutta — Fri, 24 Apr 2026 04:03:08 +0000

Chennai FOSS 2026

Earlier this month, on 18th April 2026, I had the incredible opportunity to speak at Chennai FOSS 2026, an event organized by FOSS United. If you aren’t familiar with them, FOSS United is a non-profit foundation dedicated to promoting the Free and Open Source Software ecosystem in India.

About my talk

My talk, titled "Getting started with GUI Design and Music Generation using Qt and C++," was a reflection of my recent contributions to the Season of KDE 2026.

The session shares how I, personally, as a new developer, found my way across one of my favorite projects, Mankala Engine, and started contributing in the Season of KDE 2026. I had shared my work from the Season of KDE, which included updating the GUI using C++ and QML, and also implementing elements like sounds and physics using QT. How developers can make contributions using Kirigami and other QT modules of KDE.

Most contributions are not limited to code, and I also shared the artworks I created for Mankala Engine, as well as my experience being part of Season of KDE 2026.

Here is my session PDF:

I don't like too much text, my session was mostly a live demo :)

Apart from learning about many new topics, which proved helpful to me, I also got the chance to network with other projects and contributors.

Thanks for reading 🚀

KDE email, part two: use an email client

Nate Graham — Thu, 23 Apr 2026 21:53:08 +0000

One of the many benefits of going to in-person sprints is you get to see how other people use their computers, and you can learn some workflow tricks from them. Or, you might notice areas of inefficiency and share tips of your own.

This post will be about the latter, on the subject of email.

Because during the sprint, I observed multiple people using email on their laptops in ways that are slow or ineffective:

Logging into webmail in a web browser
Switching between multiple webmail sites to manage multiple email accounts
Clicking on buttons in the webmail UI to delete or reply to messages

If you recognize yourself here, there’s a better way, I promise. And I’d like to help you achieve it!

Back in 2024, I wrote about my email workflow and offered some general tips for managing email overload in KDE. I’m going to write more in depth about this topic, today starting with…

Use an email client app.

KDE has one: KMail. If it works well for you, use it! If it doesn’t, use Thunderbird instead, it’s fine. Don’t feel guilty for not using a piece of KDE software. Nobody’s gonna excommunicate you from KDE! I’m officially giving you permission.

Maybe you use an email client on your desktop but haven’t set one up on your travel laptop yet? Well, it’s time!

Because the important part is to consistently use an email client app of some sort. Why?

Way better for multiple accounts

Most of us have 2 or more email accounts. With webmail, this becomes a pain that scales linearly with the number of accounts.

With an email client app, you can manage multiple accounts’ worth of emails in one UI. When all your accounts are managed from one app, your brain doesn’t need to learn and remember multiple UIs, and and opening new email accounts doesn’t scale the mental burden at all.

Faster to use

An email client app lets you interact with emails using learnable and consistent keyboard shortcuts. Processing emails this way is super fast, so you can get done quickly and go back to something useful. Email sucks; life’s too short to waste time on it.

Easier to access

You can access the email client app easily using the Task Switcher, Overview, or Alt+Tab, rather than letting those webmail tabs get buried among your 75 normal browser tabs and 10 pinned tabs.

Easier to leave email mode

Quit the email client app when you want to stop receiving emails.

For webmail, you’re tempted to leave it open in a tab forever, which means to avoid being constantly tortured with email notification, you’ll have to turn them off entirely, so you stop noticing emails when they arrive. This is problematic for the “keep my email open all day” approach where the whole point is being able to action new emails immediately so they don’t pile up.

Using an app that can be turned off also facilitates being a “check email once a day” kind of person, if that’s your jam. Open the app, check your email, action the important ones, delete or archive all of them, then close the app. You can carve out 5-20 minutes for email, be free of email for the rest of the day, and still keep on top of everything!

Using good tools is enjoyable

Imagine trying to manage versions or debug code without git or gdb. It would take ages and the results wouldn’t be as good. Proficiency with these tools makes you feel like a bird soaring above the clouds or a wizard effortlessly wielding powerful magic, not some clod stumbling around in the mud.

Email clients are the same way. Learn powerful tools to bolster your professional skills and feel better about the process of participating in KDE, not just the outcomes.

The Thunderbird email client is the foundation of my email system. In conjunction with other techniques — which I briefly described in the earlier post and will flesh out in more detail over the coming weeks — this is currently my email situation:

Those are all of my emails across 5 accounts. Here are just my KDE emails:

As you can see, this is completely manageable. It takes practically no effort to keep it this way, and there’s no feeling of dread when checking emails in the morning. If you’re drowning in email, you can get here too, I promise.

It starts with using an email client. If you aren’t regularly using one yet, it will take some up-front work, and some re-training, but it’s worth it: you’ll spend less time and mental resources on email and more of it on what actually matters — without taking the easy path of neglecting email and being perceived as a person who’s hard to contact or unreliable.

So get started today with KMail or Thunderbird!

Monthly Report - April 2026

Krita News — Tue, 21 Apr 2026 00:00:00 +0000

Krita 5.3.0/6.0.0 is here, and 5.3.1/6.0.1 followed soon after.

Read on for a look at development news and the Krita-Artists forum's featured artwork from last month.

Development Report

Krita 5.3.0/6.0.0 Released!

Krita 5.3.0/6.0.0 has finally been released!

However, some Windows users experienced slowdowns with 5.3.0. After much effort by users and developers trying to track down the problem, it was determined some external apps were triggering slowdowns in Qt Accessibility.

The problem was fixed with a backported Qt patch, and 5.3.1/6.0.1 released.

Fixes in 5.3.1/6.0.1

That release also contains a few other fixes. Resize Canvas's canvas size values no longer become huge after toggling 'Constrain proportions" (bug; change).

On Krita 6, incremental version failing to save and incremental backup freezing Krita (bug; change), and moving or copy-pasting a keyframe doing nothing (bug; change) were fixed. Drag-and-dropping an image no longer crashes on Wayland (change).

5.3.1.1 Released for Android

On Android, 5.3.1 introduced some regressions, which were fixed in 5.3.1.1. Editing a text field on Android 12 or older once again doesn't crash (change), which was related to fixes for the text edit popup covering text and the window panning up when using Text Tool (bug 1, bug 2; change 1; change 2).

Handling stylus buttons of some devices works again, and OnePlus stylus button (F21) is middle click (change 1, change 2), Huawei stylus double-tap gesture (Android key 718) is F25 (change).

Additionally, setting fallback languages has been disabled, as it makes the UI unusably slow (CCbug; change).

On macOS, 5.3.1.1/6.0.1.1 was released to fix an issue with Krita's built-in FFmpeg not working due to incorrect entitlements.

Further Developments

Wolthera has started working on the roadmap goal of improving HDR. In the unstable Krita Next builds, canvas decorations such as the transparency checkerboard, tool outlines, and the color sampler (bug 1, bug 2; change); reference images (bug; change); and the pixel grid (change) in are now displayed properly in HDR.

Luna continues to refine the Selection Actions Bar. An issue where the bar disappeared when toggling selection visibility was fixed (change), it's no longer interactable when covered by the pop-up palette (change), and a toggle for it was added to the selection tools' options docker (change).

Check out the Additional Changes section near the bottom of this post for more development build fixes and improvements.

Kookbook 0.3.0 released

Sune Vuorela — Mon, 20 Apr 2026 15:01:53 +0000

I recently released version 0.3.0 of my recipe manager application Kookbook – find it in git in KDE Invent or as released tarballs in https://download.kde.org/stable/kookbook/

Changes since last time is more or less “Minor bugfixes and a Qt6 port” – nothing as such noteworthy unless you aim to get rid of Qt5 on your system.

so what is kookbook?
It is a simple recipe viewer that works with semi-structured markdown. More details can be seen in the quite old 0.1.0 announcement

At some point I should do a 10 recipe example collection, but my personal collection is in danish, so I’m not sure it is going to be useful. Unless someone will donate me some handfuls of pre-formatted recipes, I will happily announce it.

KDE Mega Sprint 2026 Graz

Raresh Rus — Sat, 18 Apr 2026 13:54:00 +0000

Hello https://planet.kde.org

I am Raresh Rus, https://invent.kde.org/nmariusp , https://www.youtube.com/@nmariusp .

I took part in the KDE Mega Sprint 2026 Graz https://community.kde.org/Sprints/MegaSprint/2026 .

The sprint was from 09:00 - 19:00, Monday 2026.04.06 - Saturday 2026.04.11.
In room HS FSI 1, Inffeldgasse 11, Graz, Austria. In the Inffeldgasse campus of the Technical University Graz (TU Graz).

We were hosted by the "Grazer Linuxtage 2026" organization. Thank you Kevin Krammer.

I travelled by bus and slept almost all of the time.

The city of Graz has a population of 300,000 and is the second largest city in Austria after the capital Vienna.
Graz has a large number of well preserved pre First World War buildings.

More than 20 KDE contributors participated. Including CorneliusS and LaurenzW from the GNOME community.

Before the sprint, I created a youtube video "KDE Mega Sprint 2026 and Grazer Linuxtage 2026 #glt26" https://www.youtube.com/watch?v=56xIRyyFR3c

During the sprint, I did small gitlab Merge Requests.
Some KDE git repositories had the main readme file say that the KDE project can most easily be built using kdesrc-build. I replaced "kdesrc-build" with "kde-builder".
I saw that https://develop.kde.org/docs/getting-started/building was ready to replace https://community.kde.org/Get_Involved/development#Setting_up_the_development_environment . So we did this replacement.

I have edited the flatpak manifest of some KDE GUI apps, such that less files are present in the flatpak package file.

KDE Linux comes with kwrite preinstalled from flathub. I saw that https://github.com/flathub/org.kde.kwrite/blob/master/org.kde.kwrite.json does exist. But this flatpak manifest for kwrite does not exist in the KDE git repository of kwrite and kate.

I have encountered various issues with the licenses displayed in the about dialog of various KDE GUI apps. Scroll issues in license text viewer in Kirigami app. Not correct license being displayed. There are also differences between the license in reuse in the KDE git repository, the license shown in the GUI app's about dialog, the license shown for that app in Discover, apps.kde.org, flathub and snap store.

Also, in reuse, the license of files which come from outside the KDE community for example app icons for VLC and Blender have different licenses in the upstream git repository and in the KDE git repository.
The reuse linter prefers that we use file "REUSE.toml" instead of ".reuse/dep5".

Top issues that I have encountered: I saw Plasma Welcome Center tens of times without reinstalling operating systems or reverting VM snapshots. My hardware laptop took many minutes to start until I have disabled "Intel VMD" from the UEFI firmware screen with advanced settings.

Fedora 44 Workstation and Ubuntu 26.04 use the GNOME desktop, do not have a GNOME desktop X11 session, but I can connect using the Remote Desktop Protocol. See https://www.youtube.com/watch?v=oelT312LqFI , https://www.youtube.com/watch?v=xjfC4GGI7_w

Work is in progress to have these features available also for KDE Linux and the KDE Plasma Wayland session.
The big epics are probably: "KDE Plasma Wayland session - make it possible via command line to change the KDE Plasma Wayland session resolution to arbitrary width and height integer values", "vdagent - make it possible to paste plain text towards KDE Plasma Wayland", "vdagent - make it possible to copy plain text from KDE Plasma Wayland", "RDP server in KDE Plasma Wayland - implement plain text clipboard copy/paste", "RDP server in KDE Plasma Wayland - make it possible to log into KDE Plasma from a RDP client such as xfreerdp".

Toward the end of the sprint, we recorded a youtube video "Conclusions panel KDE Mega Sprint 2026 Graz" https://www.youtube.com/watch?v=eSCXY4nEiWI .

State of Kdenlive - 2026

Kdenlive — Sat, 18 Apr 2026 09:00:00 +0000

In 2025, the Kdenlive team continued grinding to push the project forward through steady development, collaboration, and community support. Over the past year we’ve found a nice balance between adding new features, bug fixing, polishing the user interface, and improving performance and workflow, with stability taking priority over feature creep.

We relaunched the website with a new content management system, refreshed some content and the design, and restored historic content dating back to 2002. We also strengthened upstream collaboration with the MLT developers and contributed several improvements to OpenTimelineIO.

Here’s a look at what we've been up to and what is ahead.

RELEASE HIGHLIGHTS

As part of KDE Apps, we follow the KDE Gear release cycle, with three major releases each year—in April, August, and December—each followed by three point maintenance releases.

25.04.0

This release added a powerful automatic masking tool and brought the last batch of features from our last fundraiser.

-> Read full changelog

Background Removal

The new Object Segmentation plugin based on the [SAM2][4] model allows to remove any selected object from the background.

OpenTimelineIO

We rewrote our OpenTimelineIO import and export function using the C++ library. Now you can exchange projects with other editing applications that support this open source file format.

Waveform improvements

Audio waveform generation got a 300% performance boost, along with a refactored sampling method that accurately renders the audio signal and higher-resolution waveforms for greater precision.

25.08.0

This release focused heavily on stabilization, bringing over 300 commits and fixing more than 15 crashes. Instead of major new features, the effort went into polishing and bug fixing.

-> Read full changelog

Audio Mixer

We redesigned the audio mixer bringing levels with clearer visuals and thresholds. We also did some code refactoring and cleanup. This change fixes issues with HiDPI displays with fractional scaling.

Markers and Guides

Guides and Markers got a major overhaul this release to improve the project organization.

Titler improvements

This release the titler received some much needed love like improved SVG and image support with ability to move and resize items, added center resize with Shift + Drag, and renamed the Pattern tab to Templates and moved the templates dropdown to it

25.12.0

The focus of this release cycle was on improving the user experience and polishing the user interface.

-> Read full changelog

Welcome Screen

We added a new first-run launch screen for first time users as well as added a Welcome Screen allowing to easily launch recent projects.

Docking System

We added a new, more flexible docking system that lets you group widgets, show or hide them on demand, and save layouts as separate files that can be shared or stored within projects.

Redesigned monitor

The audio waveform in the Project Monitor got a revamped interface with an added minimap.

THE ROAD AHEAD

26.04

This next release is just around the corner and brings a nice batch of nifty new features like monitor mirroring and animated transition previews, making it much easier to visualize how they will look before applying them. Additionally, dropping a transition onto the timeline can now automatically adjust its duration to match the clips above and below, saving time and reducing manual tweaking.

This feature allows you to mirror any monitor while working in fullscreen mode. It’s especially useful when working with multiple displays or collaborating with others in the editing room.

OTHER NOTEWORTHY FEATURES

Change the playback speed of multiple clips at once
Import a clip directly from the timeline context menu and insert it at the click position
Option to always zoom toward the mouse position instead of the timeline playhead
Generate audio thumbnails for sequences

ROADMAP

Our roadmap is constantly being reviewed and updated, and some of the upcoming highlights include implementing the new features in MLT, the multimedia framework which powers Kdenlive. Some exciting upcoming features include 10/12 bit color support, playback optimizations (decoding), and OpenFX support. (Shoutout to a Kdenlive community member for leading this effort). Also expected is a refactoring of the subtitle system as well as continuing to develop the Advanced Trimming Tools.

DOPESHEET

We are currently working on refactoring the keyframing system and implementing a Dopesheet, basically it is a dedicated timeline for managing and viewing keyframes from multiple effects simultaneously. This work will also introduce per-parameter keyframing (currently, once you add a keyframe to an effect, it is applied to all parameters by default). More info can be found in the last status report. This work is made possible through an NGI Zero Commons grant via NLnet.

MICROSOFT STORE

We have been working on enabling and fixing multiple modules in MLT to compile with MSVC allowing us to ship Kdenlive in the Microsoft Store soon. Another advantage is that it will allow to run unit tests on our CI for Windows.

COMMUNITY

NEW CONTRIBUTORS

Currently, the Kdenlive core team is made up of 8 active members, including 2 developers.

In 2025, 38 people contributed code to Kdenlive (including the core dev team and other KDE devs), a truly impressive number! Even more exciting, about half of them were first-time contributors, which is always great. We hope to see many of them continue contributing in the future. On behalf of the Kdenlive team, we salute you all!

SPRINTS AND EVENTS

AMSTERDAM SPRINT

In February, part of the Kdenlive core team met in Amsterdam for a short sprint, highlighted by a visit to the Blender Foundation, where we met with Francesco Siddi and he shared valuable insights into Blender’s history and offered advice on product management for Kdenlive. We also attended their weekly open session, where artists and developers present progress on ongoing projects. During the sprint, we discussed and advanced several technical topics, some highlights include:

Refining the audio workflow task
Developing a proof of concept to improve clip timecode handling
Finishing an MLT Framework patch to enable rendering without a display server (needed for Flatpak testing)

BERLIN SPRINT

The Berlin sprint was one of our most productive gatherings to date. Most of the team was there in person, and we also connected online with those who couldn’t make it. We discussed just about every aspect of the project, from roadmap planning to upcoming features and workflow improvements. Some of the highlights include:

Evaluated the current state of the Titler and discussed possible integration with Glaxnimate
Reorganized the Menu structure
Developed a proof of concept for using KDDockWidgets
Redesigned and started development of the audio clip view in the Clip Monitor

Thanks to the nice folks at c-base who kindly hosted us.

AKADEMY 2025

Akademy is always a great opportunity to exchange ideas with the broader KDE and Qt communities. One of the highlights was meeting the maintainer of Glaxnimate, where we discussed common goals and ways to collaborate. This year, Akademy will be in Graz on the 19-24 of September, and we hope to see you there.

FUNDING

Ever since our last, and very successful, fundraiser in 2022, we haven’t actively asked for donations, yet the community has continued to support us. We are very grateful for that.

In 2025, we received a total of €9,344.80 from donations (down from €11,526.61 in 2024). Around 30% of the amount was given by donors who kindly set up a recurring plan. The average donation was about €25, with the lowest amount being €10 and the highest €500.

We allocate 20% of our budget to KDE e.V. to support infrastructure costs (servers and related expenses), as well as administration, legal support, and travel. As in previous years, your contributions enable us to continue supporting Jean-Baptiste (Kdenlive's maintainer), allowing him to dedicate several days each month to Kdenlive in addition to his volunteer work.

WE NEED YOUR SUPPORT

Kdenlive needs your support to keep growing and improving. If just a quarter of the people who downloaded Kdenlive in 2025 contributed €5, our maintainers would be able to dedicate more time to the project, and it would even allow us to hire more develpers to speed up development and improve stability. Small amounts can make a big difference, please consider making a donation.

Hello old new “Projects” directory!

Matthias Klumpp — Sat, 18 Apr 2026 08:06:00 +0000

If you have recently installed a very up-to-date Linux distribution with a desktop environment, or upgraded your system on a rolling-release distribution, you might have noticed that your home directory has a new folder: “Projects”

Why?

With the recent 0.20 release of xdg-user-dirs we enabled the “Projects” directory by default. Support for this has already existed since 2007, but was never formally enabled. This closes a more than 11 year old bug report that asked for this feature.

The purpose of the Projects directory is to give applications a default location to place project files that do not cleanly belong into one of the existing categories (Documents, Music, Pictures, Videos). Examples of this are software engineering projects, scientific projects, 3D printing projects, CAD design or even things like video editing projects, where project files would end up in the “Projects” directory, with output video being more at home in “Videos”.

By enabling this by default, and subsequently in the coming months adding support to GLib, Flatpak, desktops and applications that want to make use of it, we hope to give applications that do operate in a “project-centric” manner with mixed media a better default storage location. As of now, those tools either default to the home directory, or will clutter the “Documents” folder, both of which is not ideal. It also gives users a default organization structure, hopefully leading to less clutter overall and better storage layouts.

This sucks, I don’t like it!

As usual, you are in control and can modify your system’s behavior. If you do not like the “Projects” folder, simply delete it! The xdg-user-dirs utility will not try to create it again, and instead adjust the default location for this directory to your home directory. If you want more control, you can influence exactly what goes where by editing your ~/.config/user-dirs.dirs configuration file.

If you are a system administrator or distribution vendor and want to set default locations for the default XDG directories, you can edit the /etc/xdg/user-dirs.defaults file to set global defaults that affect all users on the system (users can still adjust the settings however they like though).

What else is new?

Besides this change, the 0.20 release of xdg-user-dirs brings full support for the Meson build system (dropping Automake), translation updates, and some robustness improvements to its code. We also fixed the “arbitrary code execution from unsanitized input” bug that the Arch Linux Wiki mentions here for the xdg-user-dirs utility, by replacing the shell script with a C binary.

Thanks to everyone who contributed to this release!

KDE Sprint and Grazer Linuxtage 2026

Volker Krause — Sat, 18 Apr 2026 08:00:00 +0000

I spent the last week in Graz, Austria, attending a KDE sprint as well as Grazer Linuxtage.

KDE Sprint

Just like last year, the Grazer Linuxtage team had made rooms available for KDE people to meet in the week prior to the conference. More than twenty contributors attended, below are a few notes from discussions I have been involved with.

AppStream release notes

We use AppStream application metadata in a number of places currently:

The apps.kde.org website.
Software stores such as Flathub, F-Droid, Google Play or the Microsoft Store.
Software centers such as Discover.

In-app application metadata has so far been maintained separately though, using the KAboutData API. With KDE Frameworks 6.26 it will become possible to populate that from AppStream data as well, reducing duplicated data and duplicated translation efforts.

We also expanded how we use release notes from AppStream data:

Release notes can now also be translated.
There’s new API for accessing AppStream release notes inside an application itself. This is meant to avoid duplicated efforts for in-app release notes.
The KDE Gear release automation will now handle notes for pre-releases correctly. This means you can add release notes for users of CD builds already, those will get translated and merged into the subsequent stable release notes automatically.

There’s a few more things to do here still:

We don’t have a Kirigami-based standard component for in-app release notes yet.
The metadata converters for F-Droid and Google Play don’t handle release notes yet.

LSAN rollout on the CI

After Albert had added infrastructure for LeakSanitizer (LSAN) suppressions in the CI, we were able to enable LSAN in several more repositories which had previously been blocked on “unfixable” or intentional “leaks” outside of our control.

The increased visibility on actual issues then also helped with identifying and fixing a couple more “real” leaks, e.g. in KGuiAddons and LibKGAPI.

Qt 6.11 for Android

There has been some progress on the long overdue Qt update for our Android builds. This had been delayed as it’ll imply some rather drastic changes to the supported Android versions and devices. Lacking alternatives we will go ahead with this.

In particular, after 26.04.0 is out this means only Android 9 and higher will be supported, and 32bit ARM builds will be discontinued.

We prepared Qt 6.11 CI images and applied necessary build fixes to practically all of our apps that have Craft-based Android builds. Initial test looks promising, and some of the annoying input handling glitches seem to have been fixed.

Sentry for Android

Another Android-related topic we looked into was uploading crash information to KDE’s Sentry instance. Our Linux and Windows builds can do this since some time, and it has been a great help with identifying, prioritizing and fixing crashes.

Initial experiments got this to work quickly on Android as well, but it will require more work to do this properly and give users full control over whether they want to upload crash information or not. We explored a few options on how to do that and have a plan now, but that yet has to be implemented.

KMime move to KDE Frameworks

The long-lasting move of KMime to KDE Frameworks will finally happen early May, after the 26.04 KDE Gear release and in time for the 6.27 KDE Frameworks release.

Users of KMime will need a few minor build system adjustments for this. The CMake target name changes from KPim6::Mime to KF6::Mime, and the version number changes from KDE PIM versioning KDE Frameworks versioning. You can either replace this at once, or use the forward-compatibility approach suggested below.

The following CMake snippet replaces the previous find_package call for KPim6Mime and will handle both variants from before and after the move.

find_package(KF6Mime 6.27 CONFIG)
if(NOT TARGET KF6::Mime)
find_package(KPim6Mime 6.7.0 CONFIG REQUIRED)
add_library(KF6::Mime ALIAS KPim6::Mime)
endif()

Target names in target_link_library calls can then be switched to the new KF6::Mime already. Once the transition is complete, the above snippet can be simplified to a single find_package call for the new variant again, without needing to touch anything else anymore.

Akademy preparations

While we were in Graz the dates for this year’s Akademy were announced: September 19-24. Registration as well as the Call for Participation are open as well.

As it was already known that Akademy would be in Graz this year, we could use the opportunity to inspect venues, test food options, as well as to review and improve OSM (indoor) mapping of the conference location.

Itinerary

With a bunch of people traveling to the sprint, Itinerary also got a bit of attention of course:

Performance of opening the “My Data” page the first time was improved, by optimizing computing some of the statistics shown on that page.
A new way of sharing GraphQL query fragments should simplify maintaining support for the various OpenTripPlanner flavors in KPublicTransport. For some of the backends, the information available for rental bikes/scooters/cars became more detailed as a result of this.
Kate’s syntax highlighting got support for IATA SSIM flight schedules. That’s fallout from work on importing such data into Transitous, where it will eventually also benefit Itinerary and KTrip.

And more…

That’s not all of course, other topics included:

Improving the usability of the push services configuration in System Settings.
Enabling System Settings to configure notifications from Flatpak apps using KNotificiation.
Aligning the different ways currently used to share plain text via Purpose.
Fixing some non-obvious issues with the static builds after a recent CI image update.

There’s also reports from e.g. Kieryn, Albert and Kristen on Planet KDE with more details and other perspectives.

Grazer Linuxtage

KDE

At Grazer Linuxtage we had a KDE booth again, showing devices running Plasma, Krita and Plasma Mobile, handing out stickers as well as the famous amigurumi Konqis, collecting donations, and of course with a bunch of KDE contributors around to talk to.

Albert also did a presentation about 30 years of KDE.

Transitous

Also as part of the conference program I spoke about Transitous and what has been built for that and around that in the past two years.

Following the recent discussions about dynamic traffic data, the talk about monitoring vehicle-to-vehicle and vehicle-to-infrastructure messages was particularly interesting. The information shown on opentrafficmap.org is obtained that way, and shows how incredibly detailed this is.

There’s current positions of trams, busses, and regular cars, speed, acceleration vectors, status of all external lights, and which pedal gets pressed. Traffic lights report their current state and change timings as well as provide a full machine-readable model of their signal groups and lane relations. All of that in a standardized and (intentionally) unencrypted form.

Lots of potential in this, I wasn’t aware this went anywhere after things had gotten a bit quieter around the self-driving cars hype.

How you can help!

Bringing people together, for a small meeting or a big conference, is extremely useful and productive. The necessary travel and logistics come with costs though, which is where your donations to organizations like KDE e.V. or Grazer Linuxtage help!

This Week in Plasma: Per-Screen Virtual Desktops and Wayland Session Restore

Nate Graham — Sat, 18 Apr 2026 00:00:01 +0000

Welcome to a new issue of This Week in Plasma!

Last week over 20 KDE contributors converged on the Austrian city of Graz for our annual mega-sprint. It was a busy week, offering a good opportunity for the kinds of face-to-face conversations that can unblock stuck work and reach new consensus. Expect reports to appear on Planet KDE over the next week or two.

We skipped an issue of TWiP due to the sprint but these past two weeks have indeed been busy! Some major features landed, along with a slew of impactful UI improvements. Let’s get right into it:

Notable new features

Plasma 6.7

Each screen can now switch between any of the system’s virtual desktops independently! (Hynek Schlindenbuch, KDE Bugzilla #107302)

You can now choose your default calendar app on System Settings’ Default Applications page. (Denys Madureira, plasma-workspace MR #6468)

…And you can now middle-click on the Digital Clock widget to open the calendar app you’ve configured there. (Denys Madureira, plasma-workspace MR #6462)

You can now configure the Alt+Tab window switcher to always appear on the primary screen, rather than whichever screen has keyboard focus or the pointer on it. (Yuki Tsujii, KDE Bugzilla #329696)

You can now mark app-specific actions that you find in a search as favorites. (Kai Uwe Broulik, plasma-workspace MR #6224)

The Kicker Application Menu widget now highlights newly-installed apps, just like the Kickoff Application Launcher widget does. (Christoph Wolk, plasma-desktop MR #3649)

You can now drag-and-drop apps to the “Favorites” sections of the Kickoff, Kicker, and Dashboard widgets. (Christoph Wolk, KDE Bugzilla #383302 and plasma-desktop MR #3652)

If you find yourself captivated by a picture of the day wallpaper image, you can now right-click on it and access external information about it. (Kai Uwe Broulik, kdeplasma-addons MR #1035)

You can now optionally set Discover to quit after installing updates. (Taras Oleksyn, KDE Bugzilla #508743)

Notable UI improvements

Plasma 6.6.5

While entering the password for a Wi-Fi network using the Networks widget, the password field no longer loses keyboard focus if you happen to move the pointer away from it. (Tobias Fella, plasma-nm MR #556)

Plasma 6.7

There’s now a new standard “Badge” component in Kirigami, and many parts of Plasma have been ported to use it. (Nate Graham, kirigami MR #1847, plasma-desktop MR #3089, plasma-workspace MR #6488, systemsettings MR #399, discover MR #1290, and kinfocenter MR #262)

After

Before

The Input Method System Tray widget no longer disables the active input method if you click it while the input method isn’t currently visible. Now it just shows and hides it. (Aleix Pol Gonzalez, plasma-workspace MR #6485)

Improved the design of Discover’s grid and list items, which also slightly increases the information density of the pages that show them. (Nate Graham, discover MR #1292)

After

Before

The Kicker Application Menu widget now shows tooltips for items whose labels have been elided. (Christoph Wolk, KDE Bugzilla #515608)

System Monitor now differentiates multiple GPUs by their names, rather than by arbitrary numbers. (Bernhard Friedreich, libksysguard MR #464 and ksystemstats MR #129)

System Monitor now exposes top-level actions you can use to launch it and go straight to a specific page. These can be invoked from the app’s context menu, or via a global shortcut you set yourself. (Bernhard Friedreich, plasma-systemmonitor MR #427)

The Margins Separator widget is now added from the panel configuration dialog’s “Add New” menu, rather than the widget explorer sidebar. This matches how the similar spacer widget is added. (Antti Savolainen, plasma-workspace MR #6494 and plasma-desktop MR #3663)

The clipboard popup invoked with Meta+V now closes if it’s open when you press that keyboard shortcut a second time. (Kristem McWilliam, plasma-workspace MR #6450)

Improved how System Settings’ Shortcuts page handles being told to assign a shortcut that’s already assigned to something else. (David Bacskay-Nagy, KDE Bugzilla #484526 and KDE Bugzilla #489544)

KRunner now lets you evaluate fancy mathematical expressions more flexibly; in the past you could ask for sqrt(2) + 2 but not 2 + sqrt(2); now both are accepted. (Alex Cizinsky, KDE Bugzilla #496343)

Frameworks 6.26

The dialog that asks you if you want to launch or edit an executable text file (like a .desktop file) no longer gives you the opportunity to tell it to always do that thing. This behavior was making .desktop files un-launchable for people who selected the option to always open those types of files in a text editor. Anyone who wants to use this feature can still configure it in Dolphin’s settings. (Nate Graham, kio MR #2171)

After

Before

Removed the CFP franc from the list of common currencies, so it no longer shows up automatically for every currency conversion run using KRunner-powered searches. (Pellaeon Lin, kunitconversion MR #84)

Notable bug fixes

Plasma 6.6.4

Fixed a case where Plasma Keyboard could crash after Alt+Tabbing away from a window marked as “keep above others”. (Devin Lin, KDE Bugzilla #517087)

Worked around a bug added in Qt 6.11 that made some of Spectacle’s annotation tools unclickable. (Oliver Beard, KDE Bugzilla #515304)

Fixed a layout issue in the Activity Pager widget that made it look weird at specific non-default panel sizes. (Marco Martin, KDE Bugzilla #518451)

Plasma 6.6.5

Fixed a case where KWin could crash on logout when the session that’s closing had sent any emulated keyboard or mouse events. (Vlad Zahorodnii, kwin MR #9092)

Fixed an issue with the screen locker that could cause the buttons to malfunction and leave you unable to unlock after you pressed the Esc key in combination with various other actions with specific timings. (Akseli Lahtinen, KDE Bugzilla #515299)

Fixed an issue that made color picker functionality throughout the system return random colors on systems with certain graphics hardware. (Xaver Hugl, KDE Bugzilla #518770)

Fixed an issue that made the clock times shown on the lockscreen differ across the screens of a multi-screen setup. (DeepChirp, KDE Bugzilla #516479)

Fixed two issues that made network connections added from the Plasma setup wizard not always work properly. (Adam Williamson, KDE Bugzilla #514841 and plasma-setup MR #100)

Fixed a couple of cases where auto-hide panels might not hide properly when there were any unread notifications. (Patrick Cleary, KDE Bugzilla #519046)

Switching away from the Networks Widget in the System Tray no longer briefly makes a placeholder message appear. (Tobias Fella, KDE Bugzilla #511367)

Improved the reliability of the Weather Widget’s icon fallback behavior, making it less likely to show broken weather icons. (Ismael Asensio, kdeplasma-addons MR #1032)

Plasma 6.7

Fixed an issue that could make the Audio Volume widget not notice that a new audio device was connected and became the default one. (Oliver Beard, plasma-pa MR #393)

Using the clipboard’s non-default “Never save [non-text items] in history” option no longer breaks the ability to paste items that have been moved to the top of the clipboard history. (Christoph Wolk, KDE Bugzilla #514095)

Apps in the Quick Launch widget can once again be re-arranged. (Alex Folland, KDE Bugzilla #481922)

Fixed two quirky issues with Spectacle’s magnifier in Rectangular Region mode. (Noah Davis, KDE Bugzilla #509776 and KDE Bugzilla #509777)

Notable in performance & technical

Plasma 6.7

KWin now supports the Wayland session management protocol! This is an important step for apps to be able to remember their sizes and positions after restarting the system. The next step is for toolkits, libraries, and apps to implement support. We’re getting there! (Vlad Zahorodnii, KDE Bugzilla #436318)

Reduced the size of animated GIF images produced by apps like Spectacle that use KDE’s KPipeWire library. (Bernhard Friedrich, kpipewire MR #247)

Web Review, Week 2026-16

Kevin Ottens — Fri, 17 Apr 2026 15:17:26 +0000

Let’s go for my web review for the week 2026-16.

Sovereign Tech Agency funding - Mastodon Blog

Tags: tech, fediverse

This looks like an interesting agreement. E2EE messaging anyone? There is more of course, but I’m especially excited regarding this one.

You cannot use the GNU (A)GPL to take software freedom away

Tags: tech, foss, licensing, law

The FSF is now weighting in on the Euro-Office vs OnlyOffice situation. You have to respect the spirit of the AGPL and can’t take away freedom with extra clauses. Seems to make sense to me.

The Utopia of the Family Computer

Is Claude Mythos “Terrifying” or Just Hype?

Tags: tech, ai, machine-learning, copilot, marketing, hype, research

Are we surprised it’s mostly a PR stunt? Not at all. Of course, I agree a lot with the conclusion: we can’t trust any claim from those companies. They try to present themselves as labs but mostly try to disguise marketing as research…

Supply chain nightmare: How Rust will be attacked and what we can do to mitigate the inevitable

Tags: tech, rust, supply-chain, security

Indeed, the current supply chain model of Rust could be better. While we wait for improvements (with no sign of them coming), there are ways to try to avoid some of the common pitfalls.

https://kerkour.com/rust-supply-chain-nightmare

No one owes you supply-chain security

Tags: tech, rust, supply-chain, security, foss

Can crates.io make things easier to secure? I do think so. But this post is right that we shouldn’t forget the social aspect of the whole supply chain security conversation.

https://purplesyringa.moe/blog/no-one-owes-you-supply-chain-security/

Rust is Just a Tool

Tags: tech, rust, tools, hype

This bears repeating of course. I still wish our industry would run less on hype. It’s not specific to Rust of course.

Flat Error Codes Are Not Enough

Tags: tech, rust, failure

When possible it’s nice to nest your error types, this allows better investigation when something fails.

C++26: Structured bindings in conditions

Tags: tech, c++

Looks like a small syntax adjustment, but that indeed open the door to nice improvements.

The Global API Injection Pattern

Tags: tech, c++, dependencies, metaprogramming

This is indeed a nice pattern for dependency injection in C++ for global functions.

Can we finally use C++ Modules in 2026?

Tags: tech, c++

Probably not… This is really taking a long time to be adopted. It’s not an incremental thing at all, this doesn’t help.

Bring Back Idiomatic Design

Tags: tech, web, frontend, desktop, ux

Or why I tend to favor desktop applications (made by KDE as much as possible) rather than web applications whenever possible. It’s just more pleasant to have things which look and feel homogeneous.

The unwritten laws of software engineering

Tags: tech, engineering, failure, reliability

Those have no name… but you’ll encounter them regularly indeed.

https://newsletter.manager.dev/p/the-unwritten-laws-of-software-engineering

Writing design docs

Tags: tech, architecture, design, documentation, processes

A good primer about design documents. What’s nice about this one is the focus on the process rather than the form of the document. Indeed what matters is the shared understanding and making sure the right decision is made.

https://blog.ceejbot.com/posts/design-docs/

No agenda, no meeting

Tags: tech, meetings, documentation, remote-working

Of course I wish more meetings would follow this pattern… or not happen at all, sending me a proper document instead.

Even Ohno’s Classic “5 Whys” Example Deserves Another Why

A script element has been removed to ensure Planet works properly. Please find it in the original post.

Dolphin

Dolphin is KDE's file/folder browser manager, which also lets you connect to remote file systems and manage code repositories.

In version 26.04, Dolphin lets you add keyboard shortcuts to nearly any option in any menu, plugin or extension.

Say you find yourself often switching the order of files between order by name and order by date created. Make a shortcut and re-order with ease.

Personal Information Management

KDE's Personal Information Management software covers everything to do with email, contacts, calendars, etc.

Merkuro Calendar now boasts a re-designed schedule view and event editor. They now look more modern and show more relevant information in a more attractive way.

The venerable KOrganizer calendaring app integrated into Kontact has had a facelift and is both tidier and more informative.

Itinerary helps you plan your trips, manages all your tickets and reservations, and helps you not get lost when travelling. This new version improves its dialogs and has added new information for when travelling around Switzerland.

Kdenlive

Kdenlive is KDE's full-featured video editor.

In 26.04, you will find animated previews in Compositions that show you what a transition does even before you apply it.

Another feature you'll find useful is that you can now mirror the monitor to an external display. This will let you see the clip in the usual interface, but also on a second screen as a larger view.

A few smaller tweaks include

a timeline context menu that directly imports a clip to the project, adding it to the clicked position
an option to always zoom on the mouse position instead of the timeline playhead
automatic generation of audio thumbnails for sequences
dropping a transition to the timeline will automatically adjust its duration to the above/below clips
you can now change the speed of multiple clips at the same time.

Also in Gear ⚙️ 26.04

Audiotube boasts a fancy, brand new welcome page

KClock now shows up as an overlay on a mobile lock screen when a timer is running
NeoChat, KDE's Matrix chat client, gets a rich text editor and now supports threads!
