I'm considering buying a 1440p ultrawide display for my gaming machine (Linux Mint, Cinnamon X.Org). Is it possible to set certain games to only use the "middle" of the display? I ask because e.g. a game like League of Legends (it's my guilty pleasure, don't judge! 😂) doesn't seem like a good fit for ultrawide, and I'd rather play it at 2560×1440 "centered" with black bars on the side.

Does anybody know? Thanks!
