[Chimera-users] Fwd: Chimera crashes with MacPro show solid

The crash with solid rendering is almost surely a graphics driver bug.
The solid rendering code works correctly on many different graphics cards
and there is nothing in that code that works differently for stereo
Does the crash occur for solid rendering without stereo?
Does the size of the data set matter?
There are two solid rendering options that may avoid this crash.
These are shown in the volume dialog using the Features / Solid Rendering
Options menu entry. From the back trace you sent I see the crash occurs
when pushing the data to the graphics card and mapping the colors using
a colormap. If you turn off the option "Use colormap of size X for solids"
then different code will be used -- colors will be computed on the CPU
instead of on the graphics card. A second change that may avoid the
crash is turning off "Solids using 2D textures". This makes Chimera use
3 dimensional textures instead of 2 dimensional textures.
