Bug ID: 423295
Summary: Kwin crashed after suspend
Product: kwin
Version: 5.14.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: laur...@imbert-pro.fr
Target Milestone: ---
Application: kwin_x11 (5.14.5)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-9-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)
-- Information about the crash:
- What I was doing when the application crashed:
Waking up after suspend.
- Unusual behavior I noticed:
Login screen displays a broken picture, and kwin restarts properly after login.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
