I don't know about yours, but my mouse cursor is not a perfectly straight 2+ pixel wide solid-colored rectangle, so that doesn't really matter. As for windows edges, I'll give you that one.
However, the edge of my window happens not to be green, so it doesn't actually align with the elements of my LCD :) I just so happen not to notice it, because my eyes don't have individual pixel resolution, almost as if there was a low-pass filter of the order > 2 lambda... Food for thought!
