We are having issues with a single customer machine (until now) when initializing a MapView.
The constructor new MapView() throws an error displaying "WebGL not supported.
Now we asked the customer to run https://webglreport.com
https://webglreport.com/?v=1 displays green whereas
https://webglreport.com/?v=2 displays not supported
The mentioned application uses the 4.11 API
In a newer application (v 4.13) i found "esri/views/support/WebGLRequirements" performing a check and displaying a different message on another machine.
Is this a new check performed since 4.12 or 4.13 ?
