Flashing pixels in renders

Hello-
i’m running Zb4 on mac osx snow leopard. I have a Macpro 2.66 GHZ quad core with a radeon 1900XT, and 12 gigs of RAM.

Often when I render I get pixels flying accross my renders that seem to appear randomly. I never had this problem with ZB 3.2, What happened? Also there doesn’t seem to be a way to output frames for compositing. It would seem I will have to somehow get my model over to Maya and build new materials and render in Mental Ray. in a word, ANNOYING!
