Yes, one hint. :-) Can you provide a packet log, captured with Wireshark
or a similar tool, showing the traffic sent between the client and the
server for a failing run of a simple GLX-using app?

I suspect this is the same as freedesktop bug #3210, which idr fixed in
X.org on July 6th, 2005. We implemented a workaround in XCB for pure XCB
applications, but I got a fixed X server before I had a chance to test
the workaround I was going to implement in libX11.

If we can confirm that Sun's Xnewt has the same bug that was fixed
before X.org 6.9, then I'll ask you to test my workaround, and suggest
that you also pester Sun to fix their X server. :-)

If this is a different bug, the network trace should help in diagnosing
it further.
