FS#37 - Colors are randomly broken on open-source 'radeon' and 'nouveau' drivers.
Using an ATI Radeon HD 5770. Mesa 7.10. The colors for all environment-mapped surfaces(which means nearly all model surfaces) are randomly chosen when the renderer begins. The colors that are used are out of all the colors used by the models, rather than some random color. Also, it appears to be only entire materials that are switching to the wrong color, rather than per-surface.
How to reproduce: Open up colors.shader, and comment(//) the 'environment' part of grey25, and run the game. You will see grey25 as the color it's supposed to be, only with its envmap fixed.
My thoughts: It's either a bug in the driver or some logic error in the fragment drawing code that's only manifesting on the radeon driver. This may also affect other drivers that use Mesa, but as yet radeon is the only one that I have seen that has this issue.
EDIT: This bug also occurs on the nouveau driver for nvidia. Perhaps Gallium3D is at fault?

Reason for closing: Won't fix
Additional comments about closing: Recent updates to mesa fix this issue, but others arise. Driver bugs should not be reported here.
ATI 9700 PRO with Mesa 7.10:when I start a new game, the driver crashes and takes X with it. A reboot is necessary to get X working again.
Weird enough, the intro works fine.
Just tested an NVIDIA Geforce FX 5200 with the nouveau driver and the same problem occurs.
