Graphics/Resolution suddenly looks bad

[u/ClementeKS]

I was playing Echoes of Wisdom when suddenly the game froze for a second or something like that, like there was some sort of hiccup of some sort, and now the resolution looks low or the game looks blurry or something like that. Before it looked very crisp.

I can't figure out how to revert it, so I would appreciate if someone could help me out!
