For whatever your cairo drawing is bad. Or it's good but you can't see
it because, you did not clear the background of the pixmap by drawing
something, so it has garbage at starts.

Replacing your drawing code with:

    cairo_set_source_rgb(cr, 0.5, 0.5, 0.0); 
    cairo_rectangle(cr, 0, 0, 400, 300); 
    cairo_fill(cr); 
    cairo_set_source_rgb(cr, 0.5, 0.0, 0.5); 
    cairo_rectangle(cr, 30, 30, 30, 30); 
    cairo_fill(cr); 

make it works, I see 2 rectangles.
Also, your CopyArea calls are bad IMHO, if your
window is bigger than the pixmap.

Cheers,
