Thanks for your quick reply.
Actually I have extended the QWebPage class and overridden the
for a couple of seconds and then prints a console message. The thing
is that it works with qt4.8 and does not in qt5.
However I would very much like to use qt4.8 at the moment because
there are no packages of qt5 available for ubuntu.
Furthermore when I call the bits() method on a QImage painted through
the render method of QWebPage and inspect the data which was returned
data... Seems like a bug to me, but maybe I'm doing something wrong?
