Bug ID: 419049
Summary: KWin crashes seemingly at random
Product: kwin
Version: 5.18.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: t.krabbe+...@protonmail.com
Target Milestone: ---
Application: kwin_x11 (5.18.3)
Qt Version: 5.14.1
Frameworks Version: 5.68.0
Operating System: Linux 5.5.10-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Firefox was focused. Other than that I don't remember doing anything special.
I've been having ominous crashes every now and again, and I *feel* like this
particular crash may be related to Firefox in some way, since this particular
crash caused Plasma to restart and actually keep all applications open. I
believe such a crash has occured before, and Firefox was open then, as well.
But I don't remember this accurately enough to be sure.
The other crashes I've been experiencing have caused my system to freeze
unrecoverably, so I think those are probably caused by something else.
Many thanks in advance for looking at this!
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
