This happened to me once, also on Devil's Road. One of my team mates shot me and FF wasnt on so I didnt get any health taken away but I all I could see was green, red, and grey pixles. I think the grey was the ghillie, red was the blood (duh), and the green was a bush I was next to. It was werid because I could run around perfectly but just couldnt really see too good, I was getting shot at (by an enemy this time) so my team mate who shot me had to cover me while my screen cleared up.
And just to clarify, he wasnt too far away with his M16 or whatever, he was stood right behind me with an MK .48 (Not sure on the name) so its obviously not when you are out of range.
It only happened to me that once and if it happens again I will have more of an idea what to do... RUN AROUND LIKE CRAZY SO THEY CANT GET ME!!!
