Using glXCreatePixmap with the current Mesa packages (at least for the Intel drivers, probably for all drivers), produces the warning: WARNING: Application calling GLX 1.3 function "glXCreatePixmap" when GLX 1.3 is not supported! This is an application bug! This may be pendantically correct, but is practically speaking not workable, since glXCreatePixmap works fine, and is required for texture_from_pixmap, and hence for gnome-shell and compiz. I haven't checked what, if anything is missing for GLX 1.3 support, but the straightforward thing here seems to be to just remove the warning. If Mesa supports glXCreatePixmap when not advertising 1.3, then it should allow apps to use it.
Created attachment 362550 [details] Rendering issue using gnome-shell I have reproduced the bug while using running gnome-shell and using nouveau driver on rawhide 20090924. It seems gnome-shell is dependent on newer GLX (hence 1.3 is not supported). I checked glxinfo that states client glx is 1.4. As the result, that bug makes gnome-shell useless with too much rendering errors going on screen. Picture follows.

Warning has nothing to do with it not working on nouveau. The warning occurs on all video cards, including video cards where gnome-shell works great, it's just pointless noise.
Even "glXDestroyPixmap" warning message that can be found on attachment? Perhaps I should open another bug linked to this one.
gnome-shell is not expected to work with Nouveau at the moment, sorry. There's really not a point in filing a bug about it.
Fair enough.
I obtain the same warning using an "ATI Radeon X800 SE (R430) (PCIE)". The rendering looks perfectly fine, though!
Upstream made the warning less annoying by printing it only once, in: commit e8573033058a13bd39a0b85f48b6db64b04c65e0 Author: Tormod Volden <debian.tormod> Date: Sun Sep 20 20:20:01 2009 +0200 GLX: Warn only once about applications calling GLX 1.3 functions
