Workspace goes gray then back to normal once I save

Hi,

So I've had this issue for awhile, not just in Premiere but also in Photoshop and After Effects, pretty much all adobe software. After I have been working in the program for awhile, the whole workspace will go gray, but once I save (cntrl-s) or I drag my mouse over certain parts of the screen, the workspace goes back to normal. I never really posted about it or looked into it because it wasn't a major issue, just annoying. Don't know if it's a windows 11 thing or a computer thing or an adobe thing. Any advice would be much apprectiated.
