Bug ID: 408368
Summary: KWin Crashes When Re-sizing KWrite As Root User
Product: kwin
Version: 5.12.8
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: dasm...@electronicaidesdesign.com
Target Milestone: ---
Application: kwin_x11 (5.12.8)
Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.12.14-lp150.12.61-default x86_64
Distribution (Platform): openSUSE RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I was just running kwrite as root user and just resizing the kwrite window area
when kwin crashed.
- Unusual behavior I noticed:
When I was re-sizing kwrite the screen went blank for a second, then displayed
virtual screen #23, blanked again for a second and the kwrite window moved up
making it's toolbar go off the top of the screen.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
