Example URL:
http://webglsamples.org/aquarium/aquarium.html

Steps to reproduce the problem:
1. First I visit the page webgl testpage without the docking station plugged in and I get around 55 fps.
2. Plug in the docking station and I still get 55fps
3. Restart Chrome, while the docking station is plugged in and visit the webgl test page again: I get around 12fps.

What is the expected behavior?
I am expecting to get 55 fps in both cases

What went wrong?
Seems like during the startup you are detecting if hardware acceleration is available, but when the docking station is connected, this does not work correctly.
As long as I don't restart Chrome, it works just fine if Chrome is launched BEFORE I connect the docking station.

Did this work before? N/A 

Is it a problem with Flash or HTML5? N/A

Does this work in other browsers? Yes
