    <thetext>I tried to do this command:&quot;xrandr --output DisplayPort-0 -s 1920x1080 --scale-from 3840x2160&quot; but when I do this then my whole screen looks buggy,I see my desktop in the top left corner and everything else is black.

I asked somewhere else already and someone said that I should disable kscreen,but that doesn&apos;t help.

This is a kde problem,cause it doesn&apos;t happen with any other de.

Is there any workaround or fix?

    <thetext>Mixed DPIs are not supported on X11. Only Wayland explicitly supports this use case.
