I have the same problem; since no one has given an answer, I'd
like to repost the problem.

Interestingly, the scrambled behavior depends on the kind of
multiprocessor mode used, e.g. there is different output with
pfMultiprocess(PFMP_APP_CULL_DRAW) and pfMultiprocess(PFMP_APPCULLDRAW),
respectively.
