This is odd - I've not seen it myself. Is there a bug report against gtkglext
you can point to which covers this ?  Can you descibe what the server your
pointing to is, and what the colour depth is on your client & server - perhaps
its only certain combinations that are a problem. And what graphics card and
X driver  are you using ?
