White bar on upper corner duals creen mode

Hello,

it seems the problem is coming back. We've got rid of it for some time, but the issue returned. Are there any new infos about this proble.

We've tried GPU scaling and moved the whole windows installation to a new PC. With the new pc (latest core i12 gen. with cpu graphics) the problem expanded, that the bar will apear on both screens.

Suggestet fix, switch to GPU scaling:

Original problem from 2019:

It does not work for us on different systems. Any further suggestions?

Best regards
