I have an OpenGL ES 2 code base that runs on iOS, Android, and on PC via the PowerVR emulation libraries.
When I run this code on an LG Optimus G LGE971, I see black artifacts on my model:
My first reaction was that the near clipping plane might be the issue, but because these artifacts appear on only select devices, I do not believe that is the issue. Any other ideas on what might be causing this?
Also, this isn't captured well in the above image, but the artifacts are not static -- they move around as the model rotates, etc.
