GDB Crash

Gentoo bug: https://bugs.gentoo.org/824286


STEPS TO REPRODUCE
1.  Open krita
2.  Open colorwheel (push button on pen) with all the brushes. Click one of the two colors on the top left of the wheel repeatedly until it crashes. (crashes randomly too, but I can always replicate it using this method)

OBSERVED RESULT
Crashes with stack smashing detected.

EXPECTED RESULT
No crashing

Comment 3 Alvin Wong 2021-11-19 09:14:33 UTC 
This is a Qt bug that affects Qt 5.15 but not 5.12. On IRC, Lynx3d found that it has been reported and fixed upstream [1]. Perhaps we should try to get the fix included in KDE's Qt5 patch collection.
