Who knew, this turned out to be the problem. Running SingleThreaded  
removed the messages, so I've set my geometry's DataVariance to  
DYNAMIC and it all works great. Of course, it's a bit slower since it  
serializes the updates to that geometry, but no flashing.

Thanks for putting me on the right track, Joel!
