<pre>I think this might be related to the color rendering weirdness: On fglrx, CivBE
uses the GL_NV_half_float extension, which is not available on Mesa. Looking at
interesting words or enums that are present in one of the traces but not the
other (after apitrace dump):
* The fglrx dump mentions GL_DEPTH, GL_DEPTH_COMPONENT, GL_DEPTH_COMPONENT16,
GL_R16F, GL_RG, GL_RG16F, glColorMaski, while running under mesa does not.
* I believe the pixel formats here are probably those half floats, and if
that's unsupported by mesa, then it's no big wonder the color channels are off?
* The mesa dump mentions nan in glUniform4fv calls. That cannot be good? :P</pre>
