Me last night after extolling the virtues of the OS to my wife, trying to figure out why upping my refresh rate results in completely fucked text in Linux Mint
So far I've gathered that it's probably a similar issue to what half-rate shading does on the Steam Deck, but the fix or why it's even doing it in the first place currently eludes me
E: if anyone else has a similar issue and is on an nVidia card: try the most recent driver, not the recommended one. If that doesn't work, maybe the older one then? If still not god help you cuz the first idea worked for me
