Bug Different screen scaling setting leads to flickering

Setup:
Two screens with different window scaling setting (150% on 4k and 100% 2k). Builder on one screen and game view on the other. Enabling preview or entering play mode leads to more flickering.

Observing:
Hovering over elements in builder changes scaling in game view. This leads to flickering as the game view is repainted with the correct scaling the next frame.

Reason:
Repaint uses scaling from window that fired repaint event?

I can create a video if needed.

 

I created a new HDRP project, new scene a simple UI document with just a 100x100px box. This is using builder preview9 and toolkit preview12. It's a very minor issue as it's a somewhat obscure setup, but it does make work a bit more difficult. Hope this video helps showing the issue.
