Bug ID: 401045
Summary: Plasma crash when when switching applications via
Present Windows > Window Class
Product: kwin
Version: 5.12.6
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: k...@danieljrobbins.com
Target Milestone: ---
Application: kwin_x11 (5.12.6)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-39-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Switching application focus using "Present Windows > Window Class" (im
assuming) via Latte Dock
I was on virtual desktop 1 which would have switched to virtual desktop 2 after
using the mouse to click the window I wanted.
- Unusual behavior I noticed:
Desktop crashed (but recovered on its own) and some windows shifted upwards
vertically but not out of bounds.
Overall everything seemed to recover gracefully
- Custom settings of the application:
Application I was switching to has "force desktop" enabled via "application
settings/window rules"
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
