GPU page faults reported while playing Talos Principle 2 (demo)
RX 6600 XT, Mesa 23.2.1, Linux 6.5.4, firmware from linux-firmware commit 5105ff4b, Proton 8.0-4.
This appears to be harmless in as much as there were no obvious problems; specifically, no rendering problems were noticed and there was no GPU reset.
