Halo 3 Weird white outline around objects

I was playing Halo 3 on the MCC last night and I am on the mission “Ark”. I noticed that objects such as the ghosts, scorpion tanks, dead brute bodies etc have a white outline around them like a piece of paper glued on a backdrop. Has anyone else had this issue? I am also experiencing some frame rate drops and much more popups than halo 3 on the 360. For example random objects popping in after moving a tad closer. I knew this happened on the 360 a bit but not to this degree.
