It seems to me like webkit has to do the rendering twice: once for 2nd
monitor and once for the preview in live.


We could get some performance if the implementation would be to really create screenshot of the 2nd monitor and then scale this screenshot for use for the preview in live.

The following Qt4 classes allow direct manipulation with 2D scene:

QGraphicsScene, QGraphicsView or use directly QGraphicsWebView instead
QWebView.

Then for direct access to web page as a screenshot we could use method

QGraphicsWebView.scene().render(QPainter)

This is not jpeg specific.
