I prefer images not being shown
you're in luck, there's an option that does just that!
i agree that the image shouldn't get blown up like that but i've looked it up and Glide up/downscaling is an obscure maze so i'm afraid you'll have to endure, somehow, dealing with quote-unquote poor quality images from time to time.
even without considering functional gifs overall Glide is a colossal improvement over UIL (which is a dead library with multiple unresolved issues) so nothing is going to radically change on this front.
as usual if someone really wants to tackle this i promise to review the merge request.
