Indeed, I forced the upgrade and only share in case anyone else likes to
live on the edge.

An alternative workaround to specifying the i965 driver is to add the
following to the device section of xorg.conf:

Option "DRI" "3"

The problem appears to be a known issue with intel UHD500 / latest Mesa and
intel driver (
https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/-/issues/193).

Hopefully will be fixed soon.
