setting `MESA LOADER DRIVER OVERRIDE=i965` seems to fix the issue similar to <https bugs archlinux org task 65580|this> so I guess it s a mesa issue

nanodeath · Answer

<https gitlab freedesktop org mesa mesa merge requests 5838> might also be related alright so I ll just set that environment variable then and maybe check back in a couple months to see if it s fixed
