With window managers that support _NET_REQUEST_FRAME_EXTENTS no AWT (or Swing) windows ever show. There is only the following error message.
(:6725): Gdk-WARNING **: /home/mark/sources/gtk+/gdk/x11/gdkdrawable-x11.c:912 drawable is not a pixmap or window This was caused by the patch that delayed window realization. The window sizing logic should be moved into the "realize" signal's callback chain so that we are sure that window->window is non-NULL when I make the request to the window manager.
