Steps to reproduce the problem:
1. chrome://gpu/
2. WebGL: Unavailable
WebGL2: Unavailable
3. With Chrome 48.  WebGL is avaliable

What is the expected behavior?
WebGL should be supported with chrome new version.

What went wrong?

Currently I use cloud desktop(Citrix System) without GPU. The webGL works well with Chrome48.

But the WebGL is unavailable now after the chrome updated to 58.0.3029.110.

Any suggestion? Thanks a lot!
