Error creating WebGL context. Three js chrome?

I'm getting the error

Error creating WebGL context.
Uncaught TypeError: Cannot read property 'getExtension' of null

This is happening on google chrome 71 but I find it odd because if I open up dev tool and refresh the page it works perfectly fine I'm at a loss to what is causing this any idea's ?

It's worked perfectly fine untill today nothing has changed on the PC or browser. My drivers are all up to date, webgl is enabled...


  • Apparently it's a browser and graphic card issue

    mrdoob: The graphics card is only one of the reasons why the context can't be created

    This seems to be why unless anyone else has any other ideas... The issue is on going and not fixed it would be interesting to know why this happens though and why opening dev tools and refreshing resolves the issue for me.

    Apparently for me this was due to my graphic card being blacklisted because it's old.
