Hi,

I use Fedora 44 on x86_64, but with wip/mesa and that seems to not have
the problem. Did however have very similar fallout with www/firefox and
the consensus seems to be that it is glibc related:

https://github.com/servo/servo/issues/42695

I was able to adapt the patches from that issue and have a local
patch for Firefox. I'd try a similar approach or check if upstream Mesa
has a fix.

Kind regards,
-Tobias
