Rendering result

I have a two screen configuration:
- eDP-1, 3840x2160
- DP-1, 1920x1200
As the eDP-1 screen is hi-DPI, I have set a scaling factor = 2 in the systemsettings. This forced the font DPI at 192. However, with this configuration, the DP-1 screen is scaled up as well and the fonts are huge.

Therefore, in ~/.config/startupconfig I set the parameters'kdeglobals_kscreen_screenscalefactors' as follows:

kdeglobals_kscreen_screenscalefactors='eDP-1=2;DP-1=1;'

OBSERVED RESULT (see attachement)
For the DP-1 screen:
The fonts are scaled up at 1 for the QT applications windows
The title-bars are scaled up at 2 for all applications.
The fonts are scaled up at 2 for GTK applications.

EXPECTED RESULT
Everything should be scaled up at 1 for DP-1 screen.

There's a reason there's not a GUI option for a setting that doesn't work.

What you want does work on wayland.

I didn't know about wayland. It is working perfectly with it, thank you!
