We are probably missing something all too obvious (for example, why
scroll bars are apparently redrawn orderly).

You say yours is a tiling window manager: What happens when you manage
to remove all windows but the Emacs window from display?  This should
implicitly maximise the frame.  Does it redraw then?

And what happens when you remove the entire

   XtVaSetValues (wmshell,
		 XtNbaseWidth, (XtArgVal) base_width,
		 XtNbaseHeight, (XtArgVal) base_height,
		 XtNwidthInc, (XtArgVal) (frame_resize_pixelwise ? 1 : cw),
		 XtNheightInc, (XtArgVal) (frame_resize_pixelwise ? 1 : ch),
		 XtNminWidth, (XtArgVal) base_width,
		 XtNminHeight, (XtArgVal) base_height,
		 NULL);

call?
