I think I vaguely understand the issue...  Beryl is expecting certain
glx 1.3 functions that aren't (yet) supported in the xserver but can be
easily added.  Some Xorg developers don't want to include these
functions till glx 1.3 support is complete, while other developers have
no issues with adding the functions in a bit at a time.  I'm not sure
either group is right or wrong, but given that this has been a problem
for a while, it doesn't look like anyone is in a rush to apply the
patches.  In either case, clearly Beryl and Compiz should not just
assume that the functionality is present in the server like they
currently do.
