Bug ID: 398298
Summary: KWin crashes after resuming from hibernation
Product: kwin
Version: 5.12.6
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: cont...@yannsalmon.fr
Target Milestone: ---
Application: kwin_x11 (5.12.6)
Qt Version: 5.9.5
Frameworks Version: 5.47.0
Operating System: Linux 4.17.14-041714-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I was logging back into my locked session after resuming from hibernation. It
happens frequently that KDE needs to restart "desktop effects" on such an
occasion or after suspend (roughly every other time), but the first time that a
crash and bug reporting procedure occurred.
- Notes:
There are also some graphical glitches after resuming from hibernation or
suspend (icons get inadequate pixels, most often) which never occur on a fresh
boot.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
