Hi again, for your investigation (I think this is related with the below world loading problem topic http://www.esenthel.com/forum/showthread.php?tid=9289)

I've tested engine tutorial (15-Demo-Earth) on Android 5.1, 6.01 with Sep. update

On LG G4 Android 5.1 rendering has problem.
   

On Galaxy Note 4 Android 6.01 rendering has no problem
On PC, no problem

My game has same symptom when playing on LG G4
   

Can you let me know if the tutorial (15-Demo-Earth) will work ok if you add the following line?
This will disable depth texture usage when rendering the sky.

If this will fix the tutorial, can you try doing this to test your own project and your world as well?

Rendering artifacts on Android 5.x fixed using "Sky.frac(1)"

Thanks!
