Not sure what's different about chimera, the stereo code is generic
quad-buffered stereo OpenGL code. We don't have a stereo Mac (yet), so I
can't test it directly, but the Linux version works fine, so I would
expect the Mac version to be the same. You might try running chimera with
the --nomultisample option to see if that helps. There were multisampling
bugs on the Mac, but I thought they were fixed.
Please file separate bugs with chimera's Report a Bug dialog (in the help
menu) and attach the output of the /usr/X11R6/bin/glxinfo command (on both
Linux and the Mac) and, for Linux, the contents of /etc/X11/xorg.conf and
any __GL* environment variables you have set, and, for the Mac, the output
of "defaults read com.apple.x11". And I will try to figure it out.

P.S. Are you starting up chimera with the --stereo option or are you
switching into "sequential stereo" with the Camera tool? It shouldn't
matter, but if only one works, it would be a clue.
