As i told you on skype there is a QT implementation that doesn't redraw the entire image every time but only the damaged zones. And actually our implementation use the first method.
It is possible that the second implementation will speed up a lot the whole draw process
I thought that this was the default way how Qt handles the drawing? While developing a Qt application for N900 I noticed that paintEvent is called only when the area needs to be redrawn, for ex. when the content changes or something is overlapping etc...
