journalctl output

The system boots, then sddm leads to a black screen under Wayland. Only X11 works at this time.

I attach part of the journalctl text output after logging out from the session and switching from X11 to Wayland

Seems to be related to a bug with Mesa 24.3.1: https://gitlab.freedesktop.org/mesa/mesa/-/issues/12253

I also have the same issue in OpenSUSE Tumbleweed. Downgrading Mesa to 24.3.0 or using X11 fixes the issue for me.

The problem was solved by downgrading the mesa package
