The WebBroswer control needs to be in IE11/Edge mode in order to show WebGL content. You also need to enable GPU acceleration. See this link for details:

If you are having problems with desktop browsers too, that is most likely a video card driver issue. Be sure you are running the latest drivers for your card.
