I had the exact same problem as you, so I decided to fix it, and it worked! 
Project Settings-Rendering-ForwardRenderer-Forward Shading You need to uncheck this.It is enabled by default in VR templates. Because Forward Rendering provides a faster baseline, with faster rendering passes, which may lead to better performance on VR platforms.
But I don’t know if turning this off will affect the rest of the project after that, I’m still looking into it.
