Sounds like a driver bug. Have you tried updating the drivers?
I forgot I had even posted this lol
This issue has been gone for a while. Dunno when, dunno why, but it went away after a Mesa update, and nothing in the mesa changelog really said anything that could be remotely related, so I have no idea what got fixed. But yeah, it's no longer a problem thankefully!
