Doesn't work if your screens are too different (e.g. 4k laptop screen and 32" desktop monitor).

You can scale down from a higher resolution to make the UI perceptively the same size. You can do this with xrandr --scale OR for example the GUI in Cinnamon on Mint after you check "fractional scaling" under X mind you.

It does work for Qt and KDE at least.
