The viewer widget is a QGLWidget which does its painting asynchronously so
calling update() or repaint() doesn't really have an immediate effect.
You can use...
pixmap = QtGui.QPixmap.grabWindow(
THE_VIEWER_WIDGET.winId()
)
This will grab the fully rendered pixmap of the widget from the window
system. Take note that grabWindow(...) will also pickup any windows you
currently have over the widget.
