Application: kwin_x11 (5.16.5)

Qt Version: 5.13.1
Frameworks Version: 5.62.0
Operating System: Linux 4.19.76-1-lts x86_64
Distribution: "Arch Linux"

-- Information about the crash:
I have "Magic Lamp" and "Slide" Desktop Effects enalbed. When I minimize the window, the animation begins, I immediately move to another virtual desktop, and Kwin crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
