      Description

       The following tester tries to open the url which needs webgl, ("http://carvisualizer.plus360degrees.com/threejs") using WebEngineView, but it failed to open it. 

       

      I was using Qt 5.12.5

      It works on MacOSX.

      However, this failed on Ubuntu 18.04 and Embedded linux (Jetson TX2)

      import QtQuick 2.12
      import QtQuick.Window 2.12
      import QtWebEngine 1.3
      
      Window {
          id: root
          width: 1280
          height: 720
          visible: true
      
          WebEngineView {
              id: webView
              anchors.fill: parent
              url: "http://carvisualizer.plus360degrees.com/threejs/"
          }
      }
      

       

      The log shows as below

      [Ubuntu 18.04]
