Looks like it is being sad while trying to render a scrollbar:

Comment 2 Aleix Pol 2021-10-19 17:48:15 UTC 
Would it make sense to move this to breeze then?
Comment 3 Nate Graham 2021-10-19 19:02:10 UTC 
It's already in Breeze :)
Comment 4 Janet Blackquill 2022-02-25 17:55:32 UTC 
I can reproduce this with Fusion; it is likely either a qqc2-desktop-style or Kirigami bug. Moving to qqc2-desktop-style for now, pending further investigation.
Comment 5 Patrick Silva 2023-11-19 13:55:39 UTC 
Cannot reproduce on Plasma 6 alpha, let's consider this fixed.
