Description titusz 2019-10-22 20:12:30 UTC 
Application: kwin_x11 (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-18-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:

First case: I saved a file in LibreOffice, and when I closed the window, the Kwin exited.
Second case: When I tried to close a mate terminal, Kwin exited

- Unusual behavior I noticed:
Many of the display effect is enabled (16 GB ram, Intel i7 processor, SSD), but no lag was occurs. However, when I colse a window and the window is explodind AND I try to change the desktop with the cube effect, then the exposion becoms still and the cube turns not. After -3 seconds, the cube finih the turning and the window the explosion.
- Custom settings of the application:
Many of Kwin effect's are enabled (I know, that is it is not useful, but I want to AMaze my students ; ) )

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
