Nothing actionable in the backtrace, sadly. :( Created attachment 138230 [details] attachment-6337-0.html Ill try to reproduce with more meaningful backtrace... any suggestions on how to achieve this?

I don't think you did anything wrong. Did KWin crash too? Or just System Settings? Created attachment 138232 [details] attachment-27060-0.html I think all qt based/kde native application crashed simultaniously. I.e. dolphin, yakuake and etc. For KWin, hard to say. Wht i have notice, mine left desktop switched from screen 2 , to screen 1 for kde On Sat, May 8, 2021, 04:13 Nate Graham <bugzilla_noreply@kde.org> wrote: > https://bugs.kde.org/show_bug.cgi?id=436700 > > --- Comment #3 from Nate Graham <nate@kde.org> --- > I don't think you did anything wrong.

You can check this by installing systemd-coredump and reproducing the crash. Then, coredumpctl can be used to fetch a backtrace of kwin_wayland.

I'm sorry, you don't have a useful coredump because I forgot to mention one step. Please edit the file /etc/systemd/coredump.conf the following way: * Find a line like "#ExternalSizeMax=2G". * Replace it with "ExternalSizeMax=6G" (do not include the quote signs). After that, try to make it crash again. Then, run "coredumpctl" again and note the PID column of kwin_wayland (it was 3247 in your example). Run "coredumpctl debug PID" where you replace PID with that number. Then enter "bt" when the GDB prompt appears and copy the backtrace that appears.
