Bug 422650

Application: kwin_x11 (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-55-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
I closed a window with the "window shatter" effect. While the effect was still happened, I tried to change the desktop using mouse wheel. Window shatter froze and desktop effects crashed.

- Unusual behavior I noticed:
Desktop effects crashed

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".
