2.2.6. Avoid calls that stall the graphics pipeline

Some OpenGL ES function calls read from the framebuffer. To do this, the Mali GPU must first render the entire image before you can read back from it. This operation causes the graphics pipeline to stall so it is likely to reduce performance.

Avoid the following OpenGL ES calls:

  • glReadPixels()
    
  • glCopyTexImage()
    
  • glTexSubImage()
