ok, somewhat resolved this, but I think theres an issue in the plugin somewhere:
the flickering objects all had anim caches on them, but the animation option in FP is OFF. If I set it to ON it still flickers like before
if I disable the cache on the object itself, the flickering goes away,
so regardless of the fact it might be an issue with the cache, having the animation disabled in the FP object should have stopped the flickering no? I'm wondering if perhaps some machines are respecting the flag, and others arent...
