The post Kdenlive 24.02.2 released appeared first on Kdenlive.

We’re a few weeks after the KDE 6 Megarelease and while many people have it working well there were too many problems in KDE neon’s rollout.

We’ll be hosting two Open Door Chats on KDE meet tomorrow (Tue 16 April) where users can talk to the developers to talk about any problems you had. The access code will be posted on the KDE neon Telegram group and Matrix room or e-mail for it

Chats at 09:00 UTC (10:00 BST, 11:00 CEST) and 19:00 UTC (20:00 BST, 21:00 CEST) Tue 16 April 2024

Marknote uses QTextDocument for its WYSIWYG text editor. This is surpringly quite powerful and thanks to some code borrowed from KMail rich text editor, it wasn’t hard to implement huge part of the markdown specification.

But while QTextDocument is great, I hit quickly some limits. This is why I started fixing some of them and I already have some patches up for review in Qt.

Default table style

By default the style of the tables looks straight from the 90s, I submitted a patch to use something a bit nicer:

Old style
Old style

New style
New style

This is easy to change in the app itself and this is already the case in Marknote and NeoChat table rendering, but by default I believe Qt should provides a nice style so that apps don’t need to figure out how to overwrite the default style.

While working on this, I also noticed that the border-collapse property was not supported by the layout engine in QtQuick and only in QtWidget. This resulted in the border of the tables to be twice as thick as they should be. This was fortunately fixed by a simple patch:

Responsive images

A width and an height can be assigned to an image in a QTextDocument by using the respectives html attributes <img height="500" width="500" \>.This works correctly when the window size is known and static but less so then the window can be resized as will be the user. A common technique in web design is to add the following styles to the website:

img {
 max-width: 100%;

And while QTextDocument support some CSS properties, max-width wasn’t implemented. Adding the support for more properties in the HTML and CSS parser is quite simple as it was just forwarding the value of the max-width attribute to the QTextImageHandler, and a bit complicated was the handling of the % unit as previously only px and em was supported by Qt.

This resulted in two more patches, one for QtTextDocument and QtWidget and one for QtQuick.


Hopefully these patches will be reviewed and merged soon. Afterward I want to add support for a few more CSS properties like: border-radius for images and some other elements, as well the border-{width, style, color} properties for paragraphs to better support <blockquote /> (important when displaying emails).

Unix like systems with X11 or Wayland

All Unix like systems with either X11 or Wayland are well supported since ever.

Linux with X11 and now Wayland is for a long time the primary system on that Kate work happens.

Over the years it was, like most of the KDE applications, ported to various BSD variants.

Be it some mainstream Linux distribution like Fedora or a niche one like NixOS, Kate is available as binary package. You love BSD? From FreeBSD to OpenBSD, you can get a Kate package via your normal package system.

And in the normal case, you can just build it from source on your own, all needed patches should be in our repositories upstream. If that is not the case for your system, please help to upstream them.

Below the current state of the master branch compiled on NixOS unstable with Wayland.

How to compile Kate on your own on a Unix like system and start to help to develop it can be found out here.


Since several years there are activities in the KDE community to provide our libraries and applications for Windows.

Even if that is a non-free platform, we can reach out to new users and developers that might later be then even interested to switch a full open platform.

Progress is slow, but steady. We have Kate and some other applications in the official Windows Store and nightly build for more of them. With reasonable effort you can develop Kate on Windows with Craft.

Below the current state of the master branch running on Windows 11 inside VirtualBox.

If you like to try that, use the nighly installer linked on the Kate website.


Beside Windows, the major other non-free platform Kate tries to support is macOS.

We have nighly build available for that and you can, like on Windows, develop Kate with the help of Craft.

Below the current state of the master branch running native on my M2 ARM Mac Mini.

Same as for Windows, if you like to try that, use the nighly installer for either ARM or Intel Macs linked on the Kate website.

Other Platforms

Naturally there are more than the above mentioned operating systems around.

Beside the mobile ones like Android and iOS that are not that interesting for Kate, many other desktop operating systems exist.

Even if the Kate team itself doesn’t put active work it them, that doesn’t mean Kate can’t run there.

Without any active work on our side, for example a Kate port for Haiku was done. Some one-liner patches for that got even upstreamed.

If you work on some port of our stuff and need to upstream stuff, please contact us. Even if you work on a non-mainstream system, as long as the patches are not too intrusive, we are interested to have them.

Help us!

Naturally the most of our developers are working on the Linux or some BSD.

That means the other systems are always in need of more people to help out, both on the programming and testing side.

For Kate, testing should be easy, grab a nighly build for Windows or macOS on the Kate website. Or even better, get Craft running, that will make it easier to contribute, too.

One recent topic that needs love is the removal of DBus for Windows/macOS/Android and other systems that don’t use it normally.

If you are up to help with that, here that is coordinated. The current state is already sufficient that the nightly builds of Kate no longer hang on e.g. macOS, but still some frameworks like KIO will need more work.

Just don’t get that wrong, DBus is great on the Linux or BSD systems that use it natively, but it is a pain on systems that have no notion of DBus and leads there to hangs or the spawning of unwanted processes. Beside that, the usefulness is low there, as there are no services on the bus to communicate with anyways.

This week something big got merged: support for Explicit Sync on Wayland!

What does this do? In a nutshell it allows apps to tell the compositor when to display frames on the screen, reducing latency and graphical glitches. The effect should be particularly noticeable with NVIDIA GPUs, which only support this rendering style, and not having support for it on Wayland was the most common source of random graphical glitches and slowdowns.

This work was done by Xaver Hugl, and lands in Plasma 6.1. You can read more about it in a recent blog post he wrote on the topic!

In addition to that impactful but technical change, this was a week of many UI improvements and bug fixes as well:

UI Improvements

Improved the visual quality of cross-screen screenshots that Spectacle takes when using multi-screen setups where the screens have different scale factors (Noah Davis, Spectacle 24.05. Link)

Improved quality of blurs, pixelations, and shadows in Spectacle’s annotations (Noah Davis, Spectacle 24.05. Link)

KWrite now shows a hamburger menu by default instead of a traditional menu bar, and the hamburger menu has gained an assortment of curated actions on the top to speed up access to them (Nathan Garside and Christoph Cullmann, KWrite 24.05. Link 1, link 2, and link 3):

Just KWrite! Nothing has changed for Kate.

Filelight now throws fewer annoying modal dialog windows in your face: it now shows directory access errors using inline placeholder messages, and failures to add duplicate exclusion paths using small toasts/passive notifications (Han Young, Filelight 24.05. Link 1 and link 2)

In the “Get New [Thing]” dialogs, the warning shown at the top is now different and more warningy if the available content has the potential to run executable code on your system (David Edmundson and me: Nate Graham, Plasma 6.1 and Gear apps 24.05. Link 1 and link 2):

In Plasma’s traditional Task Manager widget, the threshold for showing any text is now smaller, so you’ll see text more often even at relatively narrow task widths. This is based on the idea that if you’re using this widget, it’s because you want to see text! (me: Nate Graham, Plasma 6.0.4. Link)

On Wayland, the Dialog Parent effect that dims parent windows when dialogs are active now temporarily disables the dimming when the dialog window is a color picker that’s currently picking a screen color (Ivan Tkachenko, Plasma 6.1. Link)

System Settings’ Virtual Desktops page has now adopted the common “controls on the header row” paradigm to increase the apace available for content (Jakob Petsovits, Plasma 6.1. Link):

In Plasma’s Power and Battery widget, the controls and UI for blocking sleep and screen locking have moved from the header into the view, matching the location of other interactive controls and preventing the header from becoming super chunky when multiple apps are inhibiting sleep and screen locking (Natalie Clarius, Plasma 6.1. Link):

System Monitor now shows a tooltip with the full text when you hover over an elided piece of text in one of the table views (Joshua Goins, Plasma 6.1. Link)

Made the header message on System Settings’ File Search page frameless and border-touching, making use of new API created to enable this purpose. This API was also used for the message in the “Get new [thing]” dialog shown earlier. So expect to see more of this kind of thing in the coming weeks! (me: Nate Graham, Plasma 6.1. Link 1 and link 2):

Folder popups invoked from a Plasma panel can now be resized if you’d like more space to see everything in them (Ivan Tkachenko, Plasma 6.1. Link)

If you preferred the old style of app launching in Plasma’s traditional Task Manager widget whereby an app’s pinned launcher would disappear when launched, you can now get that back (Niccolò Venerandi, Plasma 6.1. Link)

Middle-clicking a desktop in KWin’s Overview effect no longer instantly removes it, because this made it too easy to accidentally destroy your layout (me: Nate Graham, Plasma 6.1. Link)

The radius of rounded corners throughout Breeze-themed UI elements has now been standardized at 5px, much better than the previous random assortment of corner radii that ranged generally from 2-5px, with some being as high as 8 or 16px! This is an easily bikeshedded topic, so please try to restrain yourselves; check out all the other screenshots in this post, which feature the change—I bet you thought they looked pretty good before I explicitly mentioned that the corner radius had increased, right!? 😁 (Akseli Lahtinen, Plasma 6.1 and Frameworks 6.2. Link)

Bug Fixes

In Dolphin’s Details view, navigating to a subdirectory no longer resets the current sort mode (Felix Ernst, Dolphin 24.02.2. Link)

Gwenview no longer inappropriately blocks sleep and screen locking when simply viewing an image (Daniel Strnad, Gwenview 24.02.2. Link)

Fixed a nasty bug in Spectacle that could cause the rectangular region overlay to get stuck on screen when taking a rectangular region screenshot right after a screen recording without quitting and re-launching Spectacle first (Noah Davis, Spectacle 24.05. Link)

Plasma’s Night Light feature no longer unintentionally connects to Mozilla Location Services to geolocate you for the purpose of figuring out the Night Light transition time when you don’t have that setting turned on (Natalie Clarius, Plasma 5.27.12. Link)

Plasma no longer crashes when you close the notification that gives you an opportunity to undo removing an Icon widget (Nicolas Fella, Plasma 6.0.4. Link)

Modal font dialogs in Plasma 6 are now ugly, but at least they work again; our previous styling approach caused them to end up non-interactive and has been reverted for now pending a better solution (Nicolas Fella, Plasma 6.0.4. Link)

Discover once again shows you everything you have installed on its “Installed” page—not just an assortment of packages that depended on what distro you were using (Harald Sitter, Plasma 6.0.4. Link)

When scrolling down in one app category on Kickoff and then switching categories, random items from the former category no longer sometimes appear inappropriately on the new page (David Redondo, Plasma 6.0.4. Link)

On Wayland, the color picker dialog no longer returns incorrect colors when an ICC profile is applied to the display (Xaver Hugl, Plasma 6.0.4. Link)

Fixed a strange issue whereby items in Plasma’s list view mode Folder View popups on a panel could only be highlighted when moving the cursor downwards, rather than upwards (Akseli Lahtinen, Plasma 6.0.4. Link)

Fixed a bug that made it possible, under certain circumstances, to drag a window completely off the screen (Yifan Zhu, Plasma 6.0.4. Link)

On Wayland, the clipboard menu that appears when you hit Meta+V no longer goes underneath windows set to always be on top (Tino Lorenz, Plasma 6.0.4. Link)

In KWin’s Overview effect, the thumbnails for inactive virtual desktops are now live, not static (David Redondo, Plasma 6.0.4. Link)

Fixed a problem creating new Wireguard VPNs (Stephen Robinson, Plasma 6.1. Link)

Keyboards are no longer sometimes shown as mice on System Settings’ Mouse page (me: Nate Graham, Plasma 6.1. Link)

Rapidly toggling the “Floating” setting for a Plasma panel on and off no longer sometimes causes the panel to get stuck in a position where it’s not floating, but also detached from the screen edge (Vlad Zahorodnii, Plasma 6.1. Link)

Discover no longer mislabels apps that get removed from a Flatpak repo as being not installed when they are in fact still installed (Aleix Pol and Ivan Tkachenko, Plasma 6.1. Link)

Fixed a case where KDE apps could run out of memory when told to open certain types of malformed image files (Mirco Miranda, Frameworks 6.1. Link)

Fixed the most common crash in the Baloo file indexing service, with 113 duplicates as of the time of writing (Christoph Cullmann, Frameworks 6.2. Link)

Fixed a rare case where KIO could exhaust all memory while trying and failing to process HTTP requests under certain unusual circumstances (Harald Sitter, Frameworks 6.2. Link)

WebDAV files accessed through Dolphin or other KDE apps once again show the correct modification times (Fabian Vogt, Frameworks 6.2. Link)

Other bug information of note:

Performance & Technical

After Qt changes regressed this, changing color schemes is once again nearly instant, giving the “blend changes” KWin effect enough time to provide a smooth transition between the colors (Kai Uwe Broulik, Frameworks 6.2 Link)

Files and folders on the desktop that are copied or dragged are now made available via the Portals system, so dropping them into sandboxed apps now works as expected (Karol Kosek, Plasma 6.0.4. Link)

How You Can Help

KDE has become important in the world, and your time and labor have helped to bring it there! But as we grow, it’s going to be equally important that this stream of labor be made sustainable, which primarily means paying for it. Right now the vast majority of KDE runs on labor not paid for by KDE e.V. (the nonprofit foundation behind KDE, which I am a board member for), and that’s a problem. We’ve taken steps to change this with paid technical contractors—but those steps are small due to limited financial resources. If you’d like to help change that, consider donating today!

Otherwise, visit to discover other ways to be part of a project that really matters. Each contributor makes a huge difference in KDE; you are not a number or a cog in a machine! You don’t have to already be a programmer, either. I wasn’t when I got started. Try it, you’ll like it! We don’t bite!

Hindi Translation of Cantor and KDE connect - Season of KDE 2024 This is the second and last blog for SoK 2024. During the second half of Season of KDE, I translated Cantor and KDE connect in hindi. Cantor and KDE connect had about 1000 and 500 lines respectively. In order to translate these softwares, I took reference from google translate and AI models to improve on my translation. Translation memory did a great job in finding duplicates and helped me to avoid translating the same words again.

Software eco-design: investigating and reducing the energy consumption of software

Tags: tech, performance, energy, ecology, java, research

More work about eco-design of software. This is definitely welcome. I found this work a bit weak on the state of the art and the interview parts (10 people in the same company). But the field is so nascent that it’s to be expected I guess, PhD students have to do with what they have access to. Unsurprisingly this shows a great lack of proper tools to tackle the measurement problem. This thesis shows interesting prospects to reduce variations in measurements though, some of the proposed guidelines might help but cannot offset the hardware heterogeneity completely… The parts focusing on practical advices around Java use and deployment are interestingly easy to apply though. You need to take into account the context of your application to make the right choices of course.

Bye for now!

This is my final blog about my experience participating in season of KDE 2024. As part of my final term, I translated tellico to hindi. Tellico contains 2070 statements spanning between messages and docmessages. I used lokalize application for the translation. I hardly faced any issues during the translation work apart from some ambiguity in the translated words. Thanks Raghavendra Kamath for helping me resolve those few issues. Overall, It was an awesome experience during the entire program.
