Dear XQuartz developers,
I just want to give you a feedback about the long-awaited OpenGL stereo with X11. With the new version 2.3.2_rc1, I've tried two X11 applications that use OpenGL stereo, and it is working, again! Many thanks for your serious efforts to get OpenGL stereo working!!!
Before the final 2.3.2 version comes out, there appears to be still a bug with OpenGL stereo. There is one X11 application, Chimera, that produces the following error message upon startup:
Assertion failed: (!!req->stereoMode == !!(*a)->stereoMode), function fbconfig_compare, file glxcmds.c, line 1231. Abort trap
According to the developers of that software, glxcmds.c is not part of their software but apparently part of XQuartz. Here is an excerpt of what the responsible Chimera developer answered to me, because it might be helpful for you:
"If I were a XQuartz programmer, I would test stereo with the stereo demo program that is part of the Togl distribution, < http://togl.sourceforge.net/> (chimera uses Togl internally). Togl requires Tcl and Tk and the Tk that comes with Leopard is for Aqua, not X11, so Tcl/Tk would need to be compiled those as well."
Best regards and keep up your excellent work!
Dirk Kostrewa.
