How to reproduce:
1. Open user provided project
2. Build and run for Adreno 530 device
3. Click on Start Game button

Expected result: Object rendered correctly
Actual result: Objects (black asteroids) that use Mobile/Diffuse shader have some of their mesh triangles unrendered when scene renders objects which use Mobile/Bumped Diffuse shader

Reproduced with: 5.5.0b8, 5.5.1f1, 5.6.0b5
Project incompatible with Unity < 5.5

DUT(reproduced with):
Samsung Galaxy S7 (Adreno 530)
LG G5 (Adreno 530)

DUT (Not reproduced with):
Samsung Galaxy S5 Neo (Mali-T720)
Samsung Galaxy S6 Edge (Mali-T760)
LG Optimus G (Adreno 320)

WON'T FIX: It doesn't reproduce on newer phones with Adreno 530 (Nexus 8/Android 7.0, Pixel/Android O). So seems that it is a driver bug. Either disabling the camera with skybox or commenting out the draw call that renders this skybox fixes the issue.
