This class of issues (cache invalidation) are recurrent and only
upstream can really solve this... or we should have a post-install
action in guix package manager where we program such invalidations when
upgrading, as a _workaround_ (I guess Debian _is_ doing this, for
example)

The "cache invalidation automation via Guix" discussion is something
that predates https://issues.guix.gnu.org/issue/35683 (May 2019)

The bug you are experiencing is very similar (the same?) reported here:
https://issues.guix.gnu.org/issue/63197

...upstream is still working (?) on the issue:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/8937

All in all this (and all cache invalidation) bug is not Guix specific.

As I already proposed (https://issues.guix.gnu.org/issue/35683):

--8<---------------cut here---------------start------------->8---

we should find a way to make Guix users aware of this kind of problems
and possible workarounds they can apply

--8<---------------cut here---------------end--------------->8---

Best regards, Gio'
