Your browser does not support Mapbox GL

[fwibowo1]

I use Chrome Browser,
Use graphics acceleration when available is enabled
The Chrome flags for WebGL Developer Extensions and WebGL Draft Extensions are enabled
But the error message "Your browser does not support Mapbox GL" persisted, No chart is displayed.
Any suggestion what cause it?

What OS? What graphics card? What driver version for the graphics card?

Mapbox and DeepZoom are pretty resource intensive, so it could be something like lack of memory on your graphics card, or older hardware that isn't fully supported in WebGL.
