The nvidia driver has had this bug for a year now, still unfixed. Games will randomly crash with an Xid 109 error in dmesg. Some people (including myself) are unable to play games like Cyberpunk, Resident Evil 2-3-4-7-8 and Metro Exodus. And it’s not linked to proton either, it sometimes also crashes xorg itself, forcing a reboot. I’m starting to think nvidia will never bother fixing it.
