Quoted Jeremy Huddleston <jeremyhu@apple.com>:

George has put some extra work into GLX that I'd like to put out into the wild. You need to install 2.3.2_beta1 first, then update the X11 binary to 1.4.2-apple19 from here:

http://static.macosforge.org/xquartz/downloads/X11-1.4.2-apple19.bz2

Just download, decompress, and replace /Applications/Utilities/X11.app/ Contents/MacOS/X11 with it.

I appreciate the effort you put into this Jeremy. You helped me improve the GLX and pbproxy/xpbproxy code with your review and comments. Those of you that want OpenGL stereo support, please try using the download Jeremy mentioned with this: defaults write org.x.X11 enable_stereo -boolean YES George -- http://people.freedesktop.org/~gstaplin/
