Steps to reproduce:

1) Download attached project and open in Unity
2) Build and run project on a device
3) Once the project is launched, check the screen and you will see that half of the meshes are not rendered/ slightly visible

Expected result: All meshes should be rendered with GPU instancing enabled (check attached image)
