Why there sometimes appears black textures on the screen of my ipad air?Th pictures below shows that issue:Thanks!

Hey -

Are you using any particle effects in the level you are showing in the screenshots above? It looks like a particle effect is trying to be rendered but the settings in the material and effect are not mobile friendly.

Let me know and we can work through them -
