Ok first i'm french and i want to know why
when i move a layer with a .jpeg file (or anything else) in pixel arts, it add blur and it's not the motion blur in think, look at this: http://imageup.fr/uploads/1335647547.jpeg
But when i delete all movemements the blur vanish..
I don't know what to do! It seems that it only happend to this sort of layer (in pixels like there).
