Bug ID: 401549
Summary: Crash when switching desktop
Product: kwin
Version: 5.14.3
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: other+...@meresinski.eu
Target Milestone: ---
Application: kwin_x11 (5.14.3)
Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.15.0-39-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
This crash happens when I switch desktop during the time of "Fall apart"
desktop effect.
I wasn't able to reproduce it with standard close window effect but maybe I
wasn't fast enough.
It reproduces every time.
- Custom settings of the application:
Fall apart desktop effect is on.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
