The issue may be due to a bad Mesa update from 1:23.1.8-1 -> 1:23.2.1-1 (https://bbs.archlinux.org/viewtopic.php?id=289333). Seems to affect Ice Lake which would explain the issue being on XPS 9300. I am not a developer. Do I wait for an upstream fix? I tried putting a lock on Mesa but just got a black screen when I updated to the latest snapshot.
