OK.  So we have a simpler scenario now.  From the screenshot I cannot
understand where redrawing hangs.  Is input still functional in such a
mangled frame?  Does evaluating (redisplay t) change anything?

Two additional things you could try: What happens when you use 0
instead of 1 in the XtNwidthInc and XtNheightInc assignments like

		 XtNwidthInc, (XtArgVal) (frame_resize_pixelwise ? 0 : cw),
		 XtNheightInc, (XtArgVal) (frame_resize_pixelwise ? 0 : ch),

And what happens when you skip these two assignments entirely when
frame_resize_pixelwise is non-nil?
