Bug ID: 426078
Summary: transparent controlpanel and menus after standy
Product: kwin
Version: 5.12.9
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: liem...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.12.9)
Qt Version: 5.9.5
Frameworks Version: 5.47.0
Operating System: Linux 5.4.0-42-generic x86_64
Distribution: Ubuntu 18.04.5 LTS
-- Information about the crash:
- Unusual behavior I noticed:
After waking up from standby the control panels and menus are transparent
sometimes. I can fix this by loging out and in again.
I use the standard Kubuntu Breeze theme and I disabled transparency in the
Plasma settings.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
