Calling gdk_window_move_resize() in show isn't guaranteed to work at
all. GTK can change it, the window manager can change it. You are
going behind everyone's back, subverting the system, sometimes the
system will notice and decide to put you in line. ;-)

Is this a toplevel window? If so, use gtk_window_set_default_size()
(to simulate a user-resized size) or gtk_widget_set_usize() (to force
a minimum size).

Is this a child widget? If so, you should be setting the window size
in size_allocate, and the size you set should correspond in some
rational way to your allocation.

To set the position, use gtk_widget_set_uposition().
