[PD] GEM quirky-ness on OS X

Hi list.

I'm working on a piece that's most likely going to be shown on a Macs
running OS X and I'm running into a strange issue with GEM. The piece
involves a short video clip that moves back and forth amongst the
frames. As long as it's moving between frames, everything is fine. But
as soon as it stops somewhere, it starts alternating between the
correct colors and their opposites causing it to flash. This doesn't
happen on linux, only on OS X. Anyone know why this is happening and
how I can fix it? I've tried a variety of video formats but nothing
seems to make a difference. Also, when it flashes to the opposite
colors, it looks like the resolution changes. Weird.

I would greatly appreciate any and all tips and suggestions.
