There’s one old game that works better by chosing “Scaled by the system”; however this make other x11 apps look slightly blurry. Is it possible to either choose “Apply scaling themselves” and exclude one app from it, or exclude every other app from “scaled by the system”, so it only affect this one game?
Nope. I already created a feature request for this. Don’t have the energy to search for a link.
thanks, I would love to +1 on it if you find the link
