[VR]EarlyUpdate.XRUpdate's CPU usage increases by about 2.4ms every 10minutes if the Unity Player isn't focused on

Dec 26, 2018

Steps to reproduce:

1. Create a new project
2. Enable VR
3. Build for standalone with "Development Build" and "Auto-Connect Profiler"
4. Run the build with an HMD attached
5. Open the profiler window
6. Make sure it is connected to the player
7. Leave the player running while unfocused for at least 20 minutes

Result: CPU usage spikes start occurring, player becomes laggy and continues to become worse as time goes on
