    Description

      The QT web browsing experience has been extremely painful for years and I finally got a hint why.

      Browsing becomes unusable when the app is using OpenGL. I've modified the qopenglwidget example, see attachment.

      1 - Launch the app
      2 - Use mouse wheel to go up and down and noticed how jagged the browsing is
      3 - Close the main window (OpenGL window) and see how fluid the browsing has become
