In the last few days, any time I use my Meta Quest 2 on PC (By cable link) about 20 or so minutes in, consistently, no matter what game I'm playing or if I'm playing one at all, weird horizontal artifacts start appearing, like trying to look through broken glass on a badly bitrate crushed stream, I've tried different cables, ports on the motherboard, but to no avail. Disconnecting and reconnecting does fix it, but it does just come back again.
The issue wasn't the GPU itself so much as it was a driver update that broke it.
For future reference if anyone else encounters this issue, I have an RX 6600 and the driver version 25.5.1 caused the problem, downgrading to 25.4.1 resolved the problem.
