Bug ID: 488756
Summary: Recurring but somewhat rare SIGSEGV crash in
kwin_wayland
Classification: Plasma
Product: kwin
Version: 6.0.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: kwin-bugs-n...@kde.org
Reporter: e...@horse64.org
Target Milestone: ---
SUMMARY
I'm seeing a recurrent but somewhat rare crash in kwin_wayland that maybe
happens once a week or so on a computer I use heavily, and I'm not sure what
triggers it. It seems to be unrelated to
https://bugs.kde.org/show_bug.cgi?id=488668 which happens 1+ times a day on the
same machine. I managed to extract a backtrace of this new, more rare crash and
I believe I saw it with Plasma 5 too although I'm not sure (I didn't know how
to use coredumpctl at that time):
