Hi, I tried to run http://learningwebgl.com/lessons/lesson01/index.html on my latest chromium(a clean untainted copy)
It pop up "Could not initialise WebGL, sorry :-(". After turn on inspector, it seems it failed to get the webgl/experimental-webgl context.
The version of my build is: 59.0.3051.0 (Developer Build) (64-bit)
Also, I tried this sample on ubuntu' s chromium which is installed by apt-get, this can successfully run the sample.
The Version of apt-get chromium is: 53.0.2785.143 Built on Ubuntu , running on Ubuntu 14.04 (64-bit)

Xing, the entire contents of about:gpu is needed, not just the top of the page. You can exclude the log messages. Plaintext is fine.

to Xing, Chromium-dev
Xing, the reason that WebGL's disabled on this driver version is clear from this line:
Mesa driver 10.1.3 renders incorrectly and crashes on multiple vendors: 629434
Disabled Features: all
See http://crbug.com/629434 .
You will need to upgrade to a more recent Mesa version in order to enable WebGL.
-Ken
