Dear All,
Apologies if this has been reported/discussed before. I did look....

It appears that on a test intel imac system, the X11 8-bit visual is profoundly broken. If colors are set to 256 in X11 preferences, or launched explicitly from the command line, an xterm window is correctly drawn, but the contents of that window are white on white. The xterm still accepts input, but if applications are launched from the (invisible) command line, the resulting windows are also blank white.

This is a deal breaker for us, and I imagine other scientific users of OS X, as several of our key applications (in electron microscopy and image processing) are only available under 8-bit visuals.


If I had to guess, I'd say we're not setting the colormap correctly; please file a bug at bugreport.apple.com. As a workaround, the Tiger X11 should still work, and you might able to use the Xnest binary I posted (other users will have to help you there, I haven't had a chance to play with it beyond building it)
