Hi,
a few weeks ago obs (Open Broadcast Studio) stopped working for me.
When I run it, it does not show a window, and pressing C-c does not stop
it (I have to kill it with pkill -9 obs).
Console-output:

This problem was resolved for me with the trick from the thread at
help-guix "OBS Studio memory leak":

It also works for me.
Can we somehow automate this solution?
Best wishes,

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'
