My game uses a Tiled map for part of the background, but when the screen is scaled to the size of the device, gaps in the map appear. pardon the low quality of the following screen shot.
Notice that, behind the gear with eyes, there is a vertical orange line. This is the gap. To my knowledge, the image filter is set to nearest, and the map is rendered at an integer anyway. Also, this problem only appears when I the game is scaled, and I believe the scale at which I am getting this problem is 1.5
