If I'm using a non native resolution in the game (desktop is still the same), like 4k instead of 1080p in a game, then the steam overlay is super tiny.
Tried switching on and off the steam scale setting, nothing happened, tried it in the game in the steam overlay still nothing.
Tried all the DPI compatibility options for the game exe, for gameoverlay and gameoverlay64 and steam exe, nothing happened.

Basically the solution exists already in steam settings under accessibility, but it's for everything only.
Wish just the steam overlay ui would scale based on desktop resolution, not by the game resolution, when going with a higher resolution. I'm gonna assume it does the reverse with lower resolution, so everything will be overly large.
