XG scrolling animated texture issue
It seems that if you use XG to scroll an animated texture it get's offset vertically a tiny amount.
If you scroll it left (180) it seems to be offset downward and if you scroll it right (0) it seems to be offset upward.
Note this only seems to occur if the texture you are scrolling is animated (non animating textures are not subject to this offset bug).
An attached screenshot shows the bug and the size of the offset (I've used "lowres" to make it clearer).
