Thanks for reporting this problem.  Unfortunately, I can't reproduce it.

Please can you attach the output of 'X -multiwindow -logverbose 3', so I 
can see what visuals the server thinks should be available, and the 
output of running 'glxinfo' on your remote system.

Can you give the version of Fedora you are using, and the version of the 
libGL package you have?

No, this is not intentional.

I guess this is an unintended consequence of a change.  It would be 
useful in tracking down that change if you could identify the last X 
server release which worked correctly.

The release announce mails are a hopefully accurate summary of intended 
changes (e.g [1])
