This crash occurs on Plasma 5.20 beta too. Operating System: Arch Linux KDE Plasma Version: 5.19.90 KDE Frameworks Version: 5.74.0 Qt Version: 5.15.1 A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/291 Git commit 989e0987d70197491b5f938f1b728749e4083bb3 by Vlad Zahorodnii. Committed on 24/09/2020 at 12:47.

[Inferior 1 (process 77751) detached] Does kwin crash if you switch to OpenGL 3 render backend? Also, can I have the output of `glinfo` (you may need to install mesa-demos)? glxinfo Created attachment 131923 [details]
output of glxinfo
yes, the crash also occurs with OpenGL 3.1 backend.
(In reply to Christoph Feck from comment #10) > glxinfo no, glinfo glinfo command is not found on neon unstable and there is no mesa-demos package in its repos. Can I also have the output of eglinfo? $ eglinfo
