Yeah looks like it (only the first frame though the trace redraws the same
thing and then it looks different presumably because the prim id didn't get
reset for the second draw...).
Not sure yet how to fix it properly, those prim ids are slightly annoying
because how they are created differs completely if there's a gs or not in our
code. But somehow the primid really needs to happen per instance.
