Black Artifacts on Android in OpenGL ES 2

Question

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 art

Answer 1

The issue has been fixed. I fixed the issue by using

glTexImage2D()

with NULL for the buffer when I set up my mipmap levels, and then using

glTexSubImage2D()

when uploading the texture data into each level.
