--- Comment #16 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Observations:

On my gen6 i965 (SNB), I see that the final draw in the trimmed trace is
"messed up". In qapitrace I can see that the source texture is fine, which
means that it's that final draw that's wrong. While there are a ton of fb
incomplete/etc warnings, they don't seem to be related to the issue.

Looking at the command sequence between the two draws, there's nothing
particularly crazy. It uses texcoord's, and does something like

enable GL_TEXTURE0
glTexCoordPointer
enable GL_TEXTURE_COORD_ARRAY
glDrawArrays(GL_TRIANGLE_FAN)

I guess the fan is a bit uncommon, perhaps that's not working well in
conjunction with the tex coords?
