I have the same PITA box in my three monitor TH2GO setup. there is a thread in the Ubi forum that goes over this; it only appears in use3renders mode and ONLY in perfect mode. back off on hardwareshaders and it goes away. This sucks, I bought a second 8800GTX card just for this setup because in SLI mode "Perfect" looks amazing and with use3renders and three monitors, OH MY GOD it looks AWESOME!!!! The water and buildings... but that stupid flickering box will not be fixed by Oleg. IF you can stand having it, then you just live with it.
