Public bug reported:
My laptop screen is 3840x2160 while my external monitor is only
1680x1050. In order for the laptop monitor to be usable I have the
scaling set at 200 (this works wonderful). However, when I plug in my
external monitor it is scaled up to 200% as well making it unusable.
Attempting to scale one to 100 and the other 200 looks to be possible;
however, the Apply button keeps appearing and disappearing randomly with
no actual effect.
It looks like practically you can only set one scale for both monitors
even though the UI looks to be letting you do it.
I have tried this on Wayland and Xorg with similar results.
