backtrace
SUMMARY
Hi
I was watching a video on full screen and has few other windows like browsers,
kate and konsole were open. The screen went black suddenly and came back with
firefox crash reporter. The browser crashed because wayland connection was
lost. (KDE/QT apps survived because of compositor restarting support). I
checked coredumps and indeed kwin crashed but without any relevant logging in
journal. KCrash generated emty backtrace so I manually did it and attaching it
here. Upon basic debugging I find no apparent reason so far.
STEPS TO REPRODUCE
1. That's the difficult part. It was random and not reproducible afaik. Only
hint is the coredump.
I do not recall any previous compositor crash, at least after plasma 6.
OBSERVED RESULT
kwin_wayland crashed
EXPECTED RESULT
It doesn't crash
