Summary: Kwin crashes on some aurorae themes when clicking on minimize button

Description Michał Dybczak 2020-03-15 16:38:54 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Install additional aurorae themes like: BreezmiteForman, Auro-G
2. Apply one of them. If that matters, move buttons to the left in order: close, minimize, maximize.
3. Open any app, click on minimize button.

OBSERVED RESULT

Kwin crashes and restores, windows is not minimized. Next click on minimize button, kwin crashes again. Since I'm not using minimize button too often, so I can't be sure if that happens all the time.

EXPECTED RESULT

Window should minimize without the crash.

Operating System: Manjaro Linux 
KDE Plasma Version: 5.18.3
KDE Frameworks Version: 5.67.0
Qt Version: 5.14.1
Kernel Version: 5.5.8-1-MANJARO
OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-6700HQ CPU @ 2.60GHz
Memory: 7,6 GiB


ADDITIONAL INFORMATION

This doesn't happen on all third party themes. When I switched to Breezmite dark, there is no issue, so it's hard to tell on which themes it happens. Maybe this is because those themes are old and not updated against newer kde software?

This issue started to happen a week ago, ca. 7.03.2020 when I updated my Manjaro KDE unstable system to the newest KDE software. I'm not sure what release was it (Plasma, framework, apps?) that day.

Ah, thanks. I'll report it to the developer of this effect and hopefully, he will fix it.
