This means it's still a bug in Mesa, you're just working around it in
your application.

As we've explained, Mesa's glthread cannot make any libX11 API calls.

There has been talk about making that change, but there's not even a
specific plan yet for making it happen upstream. It doesn't change the
situation with currently shipping libX11.
