Bug 428076

Application: kwin_x11 (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-9-amd64 x86_64
Distribution: Devuan GNU/Linux 3 (beowulf)

-- Information about the crash:
- What I was doing when the application crashed:
I have reproduced this many times; it seems that when the program plays the animation for when I close a window while the desktop is magnified, KWin crashes. This happens, too, when the desktop is magnified and I minimize a window. It does not happen when I move a window, though; the animation seems to temporarily be disabled when I magnify the desktop.

- Custom settings of the application (lame attempt at translating):
Appearance: Magic lamp
Embellishment/Beautification: Crumble, Paper, Wobbly windows

(...from Venezuelan Spanish. the language I am using KDE with):
Apariencia: Lámpara magica
Embellecimiento: Desmoronar, Papel, Ventanas tambaleantes

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".
