Resolve keeps going full screen!

Hi, I am running Resolve 20 and keep having an issue, since resolve 19, where Resolve keeps expanding to full screen whenever I switch a page, (edit to cut to fusion to render, etc)
I run on a Samsung G9 oled super ultrawide and if I switch to a standard monitor it works fine.
This started happening about a month ago and Blackmagic can't figure it out.
If anyone has any ideas it would be so helpful, it makes Resolve unusable and I have had to switch back to Premiere.
