Steps to reproduce the problem:
1. Install an app that notifies when your GPU changes like gfxCardStatus
2. load a map in maps.google.com
3. There is no step 3

What is the expected behavior?
Every other browser I use doesn't trigger the use of discrete graphics.

What went wrong?
Using discrete graphics lessens battery life considerably. If I use Google maps, I have to use Safari. 

Did this work before? No 

Chrome version:  51.0.2683.0 (64-bit)  Channel: stable
OS Version: OS X 10.10.5
Flash Version: Shockwave Flash 23.0 r0

Maybe there is a html5 feature which is being handled in Google by a GL hook when it doesn't have to. I have noot delved into the source to determine what the problem is. Embedded google maps don't appear to be a problem, although sometimes loading noaa triggers the discrete graphics momentarily (but then it switches back)
