I have the same problem like your , and i hack the gdk/directfb code , add
this code when the program exit:

GdkDisplayDFB *_display = GDK_DISPLAY_DFB(gdk_display_get_default());
_display->buffer->Release(_display->buffer);
_display->layer->Release(_display->layer);
_display->directfb->Release(_display->directfb);

Unfortunatelly also has the warning like:
(!!!)  *** WARNING [still 1 objects in pool:'Window Pool'] *** [object.c:359
in fusion_object_pool_destroy()]
 (!!!)  *** WARNING [still 4 objects in pool:'Surface Pool'] ***
[object.c:359 in fusion_object_pool_destroy()]
