Anti Fingerprinting Blocks WebGL

Hi All,

so I wasn’t able to use webGL on some websites. I checked other browsers but they worked fine. I have nvidea GTX760 with the latest drivers.
Settings under secure:/settings are correct and secure://gpu/ also shows “Hardware accelerated” for both webGL versions.
Webglreport.com shows that WebGL 2.0 works fine, but for WebGL 1 it says: “This browser supports WebGL 1, but it is disabled or unavailable.” It should also be noted that after refreshing the website a couple of times the error disappears and it says: “This browser supports WebGL 1”, however refreshing seems not to be working on websites that actually use WebGL applications.

So long story short after disabling all the privacy extensions i found out that the Anti-Fingerprinting setting seems to be blocking it. When i disable it all the WebGL applications work just fine.
It seems that there is an interference between the Anti-Fingerprinting and WebGL. I don’t how it works exactly but could it be because Anti-Fingerprinting blocks certain information like screen resolution or other system information that is needed for websites to properly use WebGL? If so is there an option to whitelist certain WebGL websites?

Ps: I have Avast Internet Security and tried both the current stable and beta version of the browser. Both had the same (described) result.
