I think there might be a problem in the "double buffering" code. If you

gtk_widget_set_double_buffered( window, FALSE );

you get single exposures.

What's a single exposure?

set_double_buffered (widget, FALSE) makes that widget *not*
double buffered. widgets are double buffered by default.

I know - running his example program, on resize I get one exposure just
before and one exposure after the resize. The square is painted twice, but
it seems to different GdkDrawable's - so you get two frames, like this:

|   ||
|   ||

It seems that the drawable from the first exposure is drawn on the larger
one, leaving a gap between the two squares - hard to describe. Compile the
code and click on the main window.

Anyway: If you disable the double buffer you just get a single exposure
after the resize, and everything looks ok.
