Example URL:
https://www.youtube.com/watch?v=GyJANnCrMuY

Steps to reproduce the problem:
1. Enable zero-copy from about:flags
2. Browse the above url

What is the expected behavior?
explorer.exe should not spike.

What went wrong?
video stutters for few seconds in the beginning and explorer.exe cpu usage spikes to 10-13% and stays there. explorer keeps eating up cpu even after i close chrome.

Did this work before? N/A 

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes

GpuProcessHostUIShim: The GPU process exited normally. Everything is okay.

It only occurs with specific videos with zero-copy/gpu rasterization enabled.

enabling/disabling gpu sandbox doest have any effect.
