Whenever one image is render next to, or overlapping an other image, there will be an line between the two images.
These two images are either rendered exactly next to each other or overlapping. As you can see, there is an unwanted line between these two images.
Here is an real example from my game, zoomed at 300%
As you can see, there are unwanted lines when two images overlap. Oddly, it does not happen to the main character(the red guy).
How can I prevent this unwanted line from getting rendered?
