Canvas on top of all tool menus

Hiya,

not sure if it's a bug, but this happens from time to time. 

For some reason my canvas appears above all the other windows and, when I maximize the canvas, I cannot access my tool menus anymore. 

This doesn't happen all the time, and resetting the workspace and restarting PS fixes this temporarily. It will start behaving like this randomly. Yesterday everything worked fine the entire day. This morning I'm having this issue again.  

Using windows 10, PS 23.0.2 and a wacom cintiq pro 24 with latest drivers.

Another thing that seems to happen at the same time is that I lose some shortcuts. I can't use "F" or "Tab" anymore until I Alt-Tab out of Photoshop and go back to it.
