One of the very first things I always do in any OS is to set the desktop background to solid color, usually black. I almost never ever will see it, coz there's always going to be a window on top of it, except upon startup for some brief period of time or if I accidentally minimize everything.

I work with full screen windows. Always (tiny number of exceptional cases maybe). I switch between windows with Alt+Tab when necessary. I also have a relatively small screen, both for work and personal stuff (14" for at least 10 years now).

You do you of course.
