Canvas fingerprint is different on Chrome after a few pages reloaded

[henriquemenezes]

Hi,

I notice that the my fingerprint was changing after page refresh.

So I tested the code in Chrome, Firefox and Safari, and only the Chrome had this problem.

The Chrome versions that tested were:

• Version 48.0.2564.116 (64-bit) - problem
• Version 49.0.2623.87 (64-bit) - ok

I wrote a method to discover the difference of value for each component between reloads and I discover that the problem is the canvas component. The canvas value is changed after a few pages reload.

Thanks for the issue! While you're at it, could you please narrow down the place in canvas generation by commenting out some lines and comparing the strings?

Cannot reproduce it and OP has not specified ways to reproduce, closing. Feel free to reopen.

I got the same issue. I thinks it may because of graphic card switching (not sure).
I use Macbook pro:

2 graphic cards:

and

Chrome with user agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.62 Safari/537.36
