Display Preferences on new Mac mini (M1 chip) with Big Sur.
Everytime I start up, log in, wake from sleep, etc. I have to open display preferences to adjust the size of the screen so that I can see it in its entirety (see screenshot). The display prefs are not being saved at shutdown. Also, the screen size adjustment slider doesn't always appear as an option (see preferences in screenshot).
Mac mini 2018 or later
