      Description

      When opening a webgl page using the WebView component in QtQuick 2, the webgl page rendering suffers from intense flickering.
      I tried running similar code under QtQuick 1 with the older version of the QtWebKit import and it renders fine.

      Here are the two codes samples :

      Rendering blinks in qt quick 2 project

      import QtQuick 2.0
      import QtWebKit 3.0;

      Rectangle {
      width: 800
      height: 600

      WebView

      { url: "http://learningwebgl.com/lessons/lesson03/index.html" anchors.fill: parent }

      }

      Works fine in a qt quick 1 project

      import QtQuick 1.1
      import QtWebKit 1.0

      Rectangle {
      width: 800
      height: 600

      WebView

      { url: "http://learningwebgl.com/lessons/lesson03/index.html" anchors.fill: parent }

      }
