It sounds like what you're doing is using gtk_pixmap_set() to change
the GdkPixmap every update. Is this correct? If so, you need to
unref the GdkPixmap after you add it to the GtkPixmap. The GtkPixmap
will hold a reference to the GdkPixmap, so you can drop the reference
you got when you created it. That way, when you replace the GdkPixmap
in the next update, the old GdkPixmap will be unrefed and destroyed.
