Bug ID: 398977
Summary: kwin crash after resume from suspend
Product: kwin
Version: 5.13.5
Platform: Debian unstable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: schneider.a...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.13.5)
Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.18.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
the computer was resuming from suspend to RAM state. Usually there is a window
stating that "graphics effects were restarted" (or so, forgot the exact
wording; let me know if it matters). This time I believe this message was not
showing up, instead kwin crashed.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
