Bug ID: 413371
Summary: KWin crashed when moving borderless window between
virtual desktops on desktop grid
Product: kwin
Version: 5.16.5
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: k...@equaeghe.nospammail.net
Target Milestone: ---
Application: kwin_x11 (5.16.5)
Qt Version: 5.12.5
Frameworks Version: 5.60.0
Operating System: Linux 4.19.72-gentoo x86_64
Distribution (Platform): Gentoo Packages
-- Information about the crash:
- What I was doing when the application crashed:
I was moving a non full-screen okular window without borders from one virtual
desktop to another within the desktop grid view.
- Unusual behavior I noticed:
After the crash I assume KWin restarted, because I could continue working
without problems. However, al windows for which I hid the border had their
border back.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
