Does it repro with other video cards?
Are you using any extensions (i.e. VAR)?
"Funky changing results" plus glDrawElements could mean that you are
modifying the verts in memory before OpenGL has a chance to access
them. With VAR on, OpenGL doesn't make a copy of the elements; it's
your job to make sure they stick around until the draw has completed.
(You can know whether the draw is done or not by adding fences, or
glFlush can be used as a last resort.)
That was gonna be my next stop. I only have one mac.
The array is static, I never change it. It's created on start-up and
free'd on shutdown, never changed otherwise. The array itself is
obviously ok.
