Steps to reproduce:
1. Create a new project
2. Enable VR
3. Create a particle system
4. Enter playmode and put it in your HMDs view

Additional information: I am using the LWRP template for VR (the scene with a workshop), and when I disable the Spot Light in the Construction Light Low game object, the errors stop (particle system still running).
