I'm in the same boat. I'd like to leave Windows but since installing POP!_OS I've had issues with ending up with two versions of Firefox installed (yes snap and yes I've fixed that now). My Yubikey can't be detected until I found a post by another user with a fix. I am still yet to find a way to get VRR working.

There's no doubt that a lot of issues are user related but honestly I don't have this much trouble with Windows. This isn't the first time I've tried Linux and each and every time I find issues that I normally just give up on and revert back to Windows. I am trying though, I even purchased a second SSD dedicated for Linux.

I gotta say though Valve's proton software is amazing and without it I probably wouldn't be trying so hard to leave Windows as my primary game doesn't have native Linux support.
