Bug ID: 430197
Summary: KWin crashed when I used hot corner to present all
windows in virtual desktop
Product: kwin
Version: 5.19.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ftefrjbhfvas...@o2.pl
Target Milestone: ---
Application: kwin_x11 (5.19.5)
Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-31-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10
-- Information about the crash:
- What I was doing when the application crashed:
I used top-right hot corner to present all 34 windows in one of my four virtual
desktops, then I again used this hot corner to switch off all windows view and
KWin crashed (but reopened immediately). All of those windows were Gwenview
instances. Just when I was writing this bug report, I did the same thing and it
happened again.

Application: KWin (kwin_x11), signal: Segmentation fault
