    I am using the OpenGL ES 1.1 emulator to test a game I’m developing.
    I have a texture atlas with several images packed together in the same texture. Each image is drawn as a quad. When I draw the quads without any rotation everythings fine, however if I rotate any quad it will render an extra pixel from the image below it. This looks like a bug in the emulator. I haven’t tested yet on a real device.

    This sounds like a common problem with texture sampling and texture atlases:

    Obviously the suggestion to clamp is wrong in that thread, but further down there is a solution. If you still have problems then we can try and help you further.
