Dialogue boxes empty/cursor gone

Hi everybody,

New to the forum, searched about this topic but couldn’t find any solutions to my problems. So here I go:
Saved projects appear to have some issues with disappearing cursor line, and dialogue boxes that open up empty. Just a white field. If you click and right-click on them, it seems that the functions could oprate properly. But it’s hard to do so when you have nothing to see.

However, when I start new projects, all is ok as it should be. Until I save it and open it up later…

Please can anyone tell me what is going on and what to do about it? Would be very helpful, thank you!

For the record: this is about Cubase 9.5 Artist…
