Vendetta - theres a lot of sprite priority issues, and clipping in the first boss-fight on the back of the truck.
The sprite priority issues start to happen around level 3, I think. There's people that come out behind doors, but you see them before they come out. Also, on the ship, there are scooba-divers that swim right through the ship. I don't have images or states to back this up at this time, will try to get them in the next few days!
Clipping: see the attached pic (c.o. JacKc) - the left side of the truck is missing sometimes, happens at the first boss encounter:
