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.

Yep. Same thing here. Davinci 20 is unusable for me now.

I know that Resolve 20 has a feature where it will run in Dual Screen mode on a single Widescreen display. I never change screen size with Resolve -- it stays the same throughout whatever I'm doing. If I need to do some other operation, like copying files in the background, doing a backup, or uploading a file, I'll switch desktops (which pushes Resolve off to the side), then do what I need to do on an empty desktop, then switch back to Resolve.

I know this is possible on Mac (where I run 6 different desktops). I assume this is possible in Windows.

It is. Default shortcut is Ctrl+Windows+Arrow.

There is also a Task View icon for the Taskbar.
