When the camera is moving, the tiled map display the lines between tiled image.
Camera moving vertically screenshot, See here:
Map in Tiled Map Editor
(how to embed image into post? like <image> code
When camera moving is over, the lines disappear.
I thought CE is pack the tiled images into one texture, but it looks like every tiled image is a single object add to state when I check the code of ObjectMakerStarling. So I doubt that will affect the performance and cause some problem like the above. How to solve it?
