Bug ID: 423319
Summary: kWin crashed when using hot corner to Present Windows
Product: kwin
Version: 5.14.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: readycommunicati...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.14.5)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-9-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)
-- Information about the crash:
- What I was doing when the application crashed:
Activated hot corner to present windows (so I could switch to another one). The
hot corner was set to the top-left of the screen and was set to "Present
Windows - All Desktops."
- Unusual behavior I noticed:
Before the crash, I noticed the desktop become quite laggy for a second before
crashing.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
