Hi,
Ok, the issue here is that i am developing games for iphone. I render using OpenGLES and Texture2D. When I render a sprite using "drawSprite" from Texture2D if another sprite is overlaying this sprite and the part overlapping is the same RBGA values a stroke will appear on the parts that are overlapping. If they don't share the same RGBA values there isn't a stroke.
Has anyone experienced this?
