Sorry I just put this up in haste.
These are 2 static sprites that don't move in the layout. The smaller one is supposed to be lying on the bigger one without any gap. But if I scroll through the layout, like for example if the player has a scroll to behavior, this gap appears as the layout is scrolled through. Same for other static sprites, they seem to be skipping rows and columns of pixels as they are drawn. I hope you got it.
