Hmm, sounds like on a tiny screen you are going to have to do some tweaks on the Font Overides tab:

I'll look into some of the scaling options and see if there is something better I can do.
But to confirm -- is this something new or something that has always been the case for FARR running on super hi-res screens?
I should say, I run FARR (and my other apps) on a 2560x1440 screen, and I think it looks perfect at that high resolution.
