SUMMARY *** Plasmashell crashes immediately after launching Arma 3. *** STEPS TO REPRODUCE 1. Launch Arma 3 from launcher OBSERVED RESULT 1. Crashes with "The Wayland connection broke. Did the Wayland compositor die?" No further information from stdout is given. EXPECTED RESULT 1. Just don't SOFTWARE/OS VERSIONS Linux/KDE Plasma: Operating System: Arch Linux KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.2.1-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5800X3D 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 6750 XT ADDITIONAL INFORMATION After Arma 3 termination I'm able to relaunch plasmashell with krunner. I have 2 monitors where one is not scaled and the other is (200%). X11 apps are allowed to scale themselves. With latest plasma 5.26 there were no issues. No other proton games are affected so far. It seems to be connected with Arma 3 ability to follow HiDPi in Windows. On plain 5.27 instead of crashing, panel gone crazy, repeatedly enlarging icons and back. After few seconds plasmashell hanged making desktop unusable. Session had to be killed.
> The Wayland connection broke. Did the Wayland compositor die This generally means that kwin_wayland crashed. Can you get a backtrace of the crash, perhaps using `coredumpctl`?

See > https://community.kde.org/Guidelines_and_HOWTOs/Debugging/ > How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl There's no process related with kwin_wayland nor plasmashell to choose from. After crash occurrence of course.
If kwin_wayland would crash wouldn't title bar be affected? It seems to be present and usable.
backtrace of plasmashell with gdb: https://pastebin.com/YmYk3vVe
>The Wayland connection broke. Did the Wayland compositor die? Plasmashell isn't the one that crashed, we would need a backtrace of kwin
Like I said: coredumpctl does not contain kwin_wayland after crash. Is there any way hooking to an existing process?
Just checked: kwin_wayland never crashes during plasmashell crash. It's running all the way.
