Issue with full screen

recently almost all interface functions open in another window whenever slicer is in full-screen view.

I’m using 5.3 on Mac OS Venture Version 13.3.1 with Apple M2 Pro

Probably popups appear in the application’s screen.

Do you move the application to a different screen after you start it?

Does it help if you delete Slicer.ini settings file? (in the subfolder in your user profile folder)
