Black lines appearing on GameObject textures

Hi, im currently experiencing a problem with my game, whenever i add a game object to my scene, weird black pixely lines appear on the objects, only on certain sides, they move if i move around in the scene view, they are also visible in game.

The black lines:

Thanks in advance, Matt.

Hey Matt, try increasing the value of the Bias field of your directional light. The nasty things should disappear at one point.
