Hello @ludwig-VHS, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.
@kisak-valve I have the same issue, sysinfo: https://gist.github.com/Ristovski/5fa833b6f55a7b4857a46c83b3bf442d
Let me know if I can debug this somehow.
Edit: Duplicate of https://github.com/ValveSoftware/steam-for-linux/issues/6691
Removing MESA_NO_ERROR=1 from the environment fixes it.
Thanks for finding that @Ristovski, closing as a duplicate and because the reporting user has turned into a ghost.
I was experiencing the same issue. Downloading adriconf and setting a configuration to disable mesa errors log solved for me.
I made an little example video, for better understanding.
