--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
I sent a piglit test which should make this easier to debug:

http://patchwork.freedesktop.org/patch/45692/

I believe the problem is that gallium never notices the updated vertex size. I
haven't debugged it in detail though. As with the WebGL test, this passes on
i965 (HSW), and fails with llvmpipe and softpipe (with DRAW_USE_LLVM=false for
good measure).
