HiDPI laptop screen along side display

Hi,

I am using a Surface Book 2 (which has a 3260x2140 display) and a Full HD screen on the side.
I am currently using kde and its scale utility to scale up everything. But this make everything on the Full HD screen bigger. On the wiki I found this https://wiki.archlinux.org/index.php/HiDPI#Side_display but if I use the solution described there I get a huge performance bump (don't really know why btw), the thing I tried is

$ xrandr --output eDP-1 --auto --output DP-1 --auto --scale 2x2 --right-of eDP-1

I also tried the other way around

$ xrandr --output eDP-1 --scale 0.5x0.5 --auto --output DP-1 --auto  --right-of eDP-1

but this kinda broke everything.

Do you know what I can do to fix this without running at 10 fps ?
