If this is on iR with a moderately recent Performer, I'd bet that this
is because Billboards are now being done in GL instead of inside Performer.

I'd try:

     pfFeature(PFFTR_GLSPRITE, PFQFTR_FALSE);

somewhere at the beginning of your program (before the pfMultiprocess I guess)
to force Performer to go back to doing sprites in software and see if that
fixes your problem.

Either way, it sounds like a pfBug.
