Of course, this effect varies from image size and different things I can't replicate. But either way it's always a similar effect. This has also happened on every graphics card I've used before. It seems what it's doing is taking a part of the image and moving it left and/or right a pixel. So it seems the smaller the image, the closer it gets to the opposite side, causing it to clip like Crow posts.
It doesn't seem like it's entirely the same thing, but it seems like one in the same problem.
