Yikes! This sounds like an initializiation problem that we need to
fix. Curious: by any chance are you running with a pfPhase now that
is NOT the default (FREE_RUN)? We have recently fixed the logic for changing
phase here to be more robust and I can imagine that with the old
logic you might have you needed that first pfFrame to happen when not
NON_DEGRADING.

Thanx for chasing this down!
