There isn't any buffering of the image done. You'll have to capture the
expose event and repaint it yourself. You can use a pixmap to act as
your 'canvas', which the drawing area then displays. IIRC there is a
scribble example that does this. 

Alternatively there is a more complete canvas widget in Gnome.
