I tried to use search but didn't find anyone having similar issues.

If I maximize for example browser (tested with FF and Chrome) to one of the split, I'm not able to open applications from taskbar. They will open behind that maximized window.

This used to work until couple of months ago. I'm using Windows 11 and DisplayFusion Pro 9.9 from Steam.

Hey Owen, beta version seems to have fixed my problem. Thanks a lot!
