Cachy has been basically rock solid for me, after figuring out a couple nvidia issues. The biggest problem I faced was trying to understand wine/proton prefixes for restoring saves files on some of my older games. Though I’m running Plasma which I guess is kinda “vanilla” compared to these fancier DEs. Props to the Cachy team and the Arch Wiki team for having such a vast wealth of information available that’s pretty easy to follow!
