We have a user that can run WebGL and see the spinning square, but their initialization fails.  
The machine they use is a Dell E5510 running Windows 10, which is about 9 years old.

Do you have any idea what the problem may be or if something they can do ?

RuntimeError: The browser supports WebGL, but initialization failed.

Hi SpaceStation22,

I’m going to move this to the CesiumJS category since it is related to rendering in CesiumJS. Hopefully that will give it more visibilty to others who might have had a similar issue.
