--- Comment #12 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The problem draw appears to be the one at call 838845. The previous one 838747
still doesn't show any bits of the model.

It uses a vertex program (ARB_fp) with indirect constbuf accesses... I'm
assuming it's a vertex program issue since the rasterized geometry seems to be
quite off.

Have yet to analyze how this gets transformed to TGSI and whatever i965 uses.
