Wallpaper does not cover all screen on Mac mini 2018 and 5k screen
I have the LG 5k screen connected to a Mac mini, and every couple of days the wallpaper does not cover the whole screen. The only way I can make it full screen again is to logout and log back in.
I've tried many things:
- changing the wallpaper but it is not saved when I log back in
- trying to put a colour instead of picture, but it is reverted back on each login as well.
Is there a way to force a full screen wallpaper, or to force keeping my settings? (like no wallpaper but a background colour)
Mac mini 2018 or later
