Describe the bug
Scaling should be consistent no matter how wide the image is, since vertical resolution is what determines the quality of the picture.
Also, on fullscreen everything is just too big, even on Steam Deck. When I have the window only occupy the right half the scaling actually looks nice and correct.
To reproduce
Have Switchfin open, maximise it, then have it only fill up half your screen.
