How to reproduce:
1. Open the attached project
2. Observe the "Main" scene, notice that there are two GameObjects, one of them uses GPU Instanced material
3. Build and run to device (Daydream is set as default VR SDK, but the issue reproduces on Cardboard and GearVR SDK's as well)

Expected result: Both GameObjects are rendered the same
Actual result: GameObject that has instanced GPU material is producing visual artifacts, is not rendered correctly
