This week in KDE: Qt apps survive the Wayland compositor crashing

Saturday, 11 March 2023 | Nate Graham

Thanks to the heroic work of David Edmundson, Qt apps (including all KDE software) in Plasma 6 will now survive when the Wayland compositor crashes! This is huge! And work is ongoing to add this functionality to other common app toolkits, such as GTK.

Beyond that, Plasma 6 porting work continues, with more and more people using it daily. Not me yet, because I’m a scaredy-cat about this kind of instability and am waiting for it to converge a bit more 🙂 But hopefully soon! Meanwhile, check out what else happened:

New Features

Konsole Now works on Windows! In addition to making the app possible to potentially distribute on Windows, this means that Windows-distributed KDE apps that have an embedded Konsole view like Kate can now actually embed Konsole itself, instead of an inferior terminal view (Waqar Ahmed and Christoph Cullmann, Konsole and Kate 23.04. Link 1 and Link 2)

User Interface Improvements

Spectacle now always shows a notification when taking a background-mode rectangular region screenshot (with Meta+Shift+PrintScreen by default) and also no longer quits if its main window happened to be open while any such notification disappears (Noah Davis, Spectacle 23.04. Link 1 and link 2)

For new users (not existing users), the system will now sleep after 15 minutes of inactivity by default, and will generate correct power profiles for convertible laptops (Plasma 5.27.3, me: Nate Graham, Link 1 and link 2)

On Discover’s app pages, the rows of buttons now become columns for narrow windows or the mobile interface, and their layout is streamlined and improved as well (Emil Velikov, Plasma 5.27.3. Link):

Discover mobile view showing "Documentation," Website," and "Share" buttons in a column

Welcome Center now has a mobile-friendly layout. The content itself is still fairly desktop-focused, but this will soon change as well! (me: Nate Graham, Plasma 6.0. Link):

In the Plasma Wayland Session, the Ctrl+Alt+Scroll up/down shortcut that switches virtual desktops has been changed to Meta+Alt+Scroll up/down to avoid blocking app-specific shortcuts and also generally comply with the standard that global actions use the Meta key (me: Nate Graham, Plasma 6.0. Link)

When using the Kickoff Application Launcher’s setting to use a grid view for non-favorites views, this now affects the All Applications view too (Tanbir Jishan, Plasma 6.0. Link)

Improved how the SDDM login screen works with a touchscreen in the Plasma Wayland session: touch input works at all, tapping the Virtual Keyboard button now opens it, and the keyboard layout list can now be scrolled with a swipe (Aleix Pol Gonzalez and me: Nate Graham, Plasma 5.27.3 and Frameworks 5.104. Link 1, link 2, and link 3)

Significant Bugfixes

(This is a curated list of e.g. HI and VHI priority bugs, Wayland showstoppers, major regressions, etc.)

KRuler now works properly on Wayland, and can now be moved or resized like on X11 (Shenleban Tongying, KRuler 23.04. Link)

Fixed another way the powerdevil power management subsystem could crash with certain multi-screen setups (Aleix Pol Gonzalez, Plasma 5.27.3. Link)

Fixes a way that apps could crash in the Plasma Wayland session when a display goes to sleep (Aleix Pol Gonzalez, Plasma 5.27.3. Link)

Night Color now works on ARM-powered devices that don’t support “Gamma LUTs” but do support “Color Transform Matrices”! It still doesn’t work on NVIDIA GPUs because they don’t support either of them (Vlad Zahorodnii, Plasma 5.27.3. Link)

Red and blue color channels are no longer sometimes swapped while screencasting in the Plasma Wayland session (Aleix Pol Gonzalez, Plasma 5.27.3. Link)

Image buttons in Breeze-themed GTK apps are now displayed correctly (Janet Blackquill, Plasma 5.27.3. Link)

Fixed two major crashes in Plasma related to actions that would show window thumbnails in the Task Manager (Fushan Wen, Frameworks 5.104. Link)

Other bug-related information of interest:

Automation & Systematization

Re-organized to have a more straightforward structure and make it easier to find stuff (Carl Schwan. Link)

Wrote some documentation about KRunner metadata (Alexander Lohnau, Link)

Web Presence is now live! This web page showcases the best KDE software to use for professional, technical, scientific purposes, including by NASA and Barcalona’s ALBA Synchrotron. has been overhauled to showcase the latest state-of-the-art in KDE’s Kirigami app development framework:

Thanks to Carl Schwan, the KDE Promo team, and many others for making these impactful changes happen!

How You Can Help

If you’re a user, upgrade to Plasma 5.27! If your distro doesn’t offer it and won’t anytime soon, consider switching to a different one that ships software closer to its developer’s schedules.

If you’re a developer, consider working on known Plasma 5.27 regressions! You might also want to check out our 15-Minute Bug Initiative. Working on these issues makes a big difference quickly!

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!
