Severe gradient banding

Reported by alemaalt...@gmail.com, Apr 19 2016 
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36

Example URL:
https://squarific.github.io/GradientCreator/

Steps to reproduce the problem:
1. Make the slider small
2. Watch the gradient only being applied over a 1 percent range instead of over 1 pixel

What is the expected behavior?
Smooth gradient

What went wrong?
I think it for some reason only calculates the color once per percentage instead of once per pixel.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? Yes

Accidental delete of comment 1,

Forgot to mention: This also happens on canvas

Might be related to https://bugs.chromium.org/p/chromium/issues/detail?id=41756 but it mentions so many different issues on gradients that I couldn't tell.

The reason I think its not related is cause this issue only seems to happen on linux.

Extra test case taken from that link that also shows the issue: http://jsfiddle.net/3fe2a/

I also tested vertically and there it seems to work making me think it is related to this comment. Maybe when this was fixed it didn't make it to the linux version somehow? https://bugs.chromium.org/p/chromium/issues/detail?id=41756#c31

@alemaaltevinden - using M49 (current Chrome stable), things look more-or-less okay to me with the jsfiddle example. The GradientCreator site seems to be down (or, at least, not doing anything). 

Can you double-check w/ M49 and/or point me at another example that might show the problem?

Using 50.0.2661.75 (Official Build) (64-bit) it looks ok. I guess this issue can be closed then.
