Bug ID: 416417
Summary: Kwin crash when activating desktop grid via screen
corner
Product: kwin
Version: 5.17.90
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: kishor...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.17.90)
Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 5.4.12-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
I moved the mouse toward the screen corner to activate the desktop grid effect.
However, kwin does not crash if I do it again. I had an external monitor
connected to my laptop at the time.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
