SUMMARY
When i full screen a browser (brave, cachy browser, edge) it will usually but not always display the top incorrectly. Sometimes you get duplicate tabs/menues one ontop of the other. Other times its once but not in the correctly place. Where you click and where the buttons are displayed no longer align. 
Additionally, if you go to where you should pull it out of full screen mode and grab the window, it will resize back down, but the top is just missing. 

STEPS TO REPRODUCE
1. Full Screen Browser
2. 
3.

Realized it appears to be only chromium based browsers.

Hi - if you're referring to maximizing when referencing a full screen browser, then I think this is the same underlying issue as an existing bug report that I'm merging this in with. There seems to be a consistent thread of window rendering issues with Chromium browsers using client-side decorations (no system title bar) having issues being maximized on devices with NVIDIA graphics cards.
