This is the same issue I have on Fedora 37 (also posted on this forum). Apologies if this has already been mentioned (quite a bit to take in above). I have noticed that the area accessible via the mouse is more, if Fedora's default driver is used (in my case NV138). Nvidia's driver restricted the area quite a bit in that I couldn't get to some parts of the menu.
For me, this is only an issue with Wayland, Xorg is fine. When in Wayland, pressing Alt+Tab makes the full screen accessible again, so at least there is a workaround.
