Bug ID: 415079
Summary: KWin segmentation fault
Product: kwin
Version: 5.16.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: rilpi...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.16.5)
Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-24-generic x86_64
Distribution: Ubuntu 19.10
-- Information about the crash:
- What I was doing when the application crashed:
When I wake my computer after suspending, there is some graphical
glitches in icons's text in desktop. So I run these commands (got it from
internet):
/usr/bin/kquitapp5 plasmashell; plasmashell > /dev/null 2>&1 & disown;
sleep 2; exit
In order to reset plasmashell and fix the glitches. It works!
- Unusual behavior I noticed:
Nothing except a window telling me that KWin has crashed right after I
run the commands.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
