Question: Are you running in Falcon or TT mode when this happens, or in
ST / STE mode? Or does it happen in both modes?

Where did you position your Hatari window before switching to
fullscreen mode? In the center or in a corner of the screen?
Also, was this in Falcon/TT mode or in ST/STE mode?

At least this works fine for me. I think this depends on your Window
