backtrace

Tested on 54b694638b, probably triggered by https://invent.kde.org/graphics/krita/-/commit/b4d5ce6af63ee75fd435f3a8a35a8e234d8cd943

Backtrace seems pretty useless, the crash appears to be somewhat internal to Qt.

I cannot reproduce it here. Though I don't have RTL enabled.
Comment 2 Alvin Wong 2022-02-18 07:41:24 UTC 
You may need to repeat it multiple times for it to trigger, but it always happen eventually for me. This is for Windows only though.

Comment 4 Alvin Wong 2022-03-08 05:16:47 UTC 
I was mistaken. This is not a regression and can be reproduced with 5.0.0.
