Hi there,

just recently the tiling patches for r6xx went into git master. I noticed that
r600c works fine with these, but r600g breaks with ColorTiling enabled. To get
correct visuals out of the gallium driver I have to disable tiling first, then
it works again.

Seems like r600g misinterprets the tiling state of the framebuffer. The visuals
are similar to the ones you got when patching mesa with the tiling patchset,
but forgetting to do the same for the ddx.

Greets,
Tobias
