Working on a java game that uses some pngs images for icons/textures. A few images ( fewer than 5, out of dozens ) are showing some odd parallel "artifact" lines. They move with the image, are certainly not in the PNG itself.
I can't figure out what's causing it. Using slick2d, lwjgl. I've tried slcik2d and opengl methods of clamping textures but that didn't help.
This black line is showing off the right-hand side of an icon (maybe 50% of the actual image width away). It should not be there.
