In my application, I render plane over plane. Lower plane has Z = 0, second one has Z = 0.5. If I render them (lower first), I got missing part of render, as shown on picture
On iPhone 4 and desktop (using ES emulator), there is everything correct and no problem. What could cause this bevaiour ?
Same problem occurs also for other parts of scene, like tracks, tubes (green and blue on this picture). Problem occurs, when I move camera
