Pixel problem?

[Spreadshot]

ok, so ive been having these graphics glitches ever since i got the game. they stay on any settings from low to ultra, and they are on every edge of every object including shadows and objects covered in light and quite often on flat surfaces like the sides of houses thanks to the windows and move along the edges continually when you move, making it hard to detect whats an enemy and whats the game having pixel problems. anyone know of a fix or is this something thats happening to others that tripwire will patch?

System specs are
Windows 7 ultimate 64 bit
AMD Phenom x4 @ 3.0Ghz
Nvidia EVGA 560 superclocked
4 Gigs DDR3
Screen Resolution 1600x900

yes, its alot harder to get them to show up in pictures, if i had the fps for a video it would be much easier to see. the first pictures the yellow pole, the second the moonlight on the floor and the third the clothesline. if i can manage later on ill try to get something with fraps on it. still, any idea what causes that?
