I don't think so -- a window only gets drawn when something has changed.
So I expect the draw command will just perform the (single) redraw
before taking the snapshot rather than after.

Re-installing shouldn't be essential.  The changes I know of were:
	fixes for the problems you found
		(src/bin/geomview/common/motion.{c,h},
		src/bin/trigrp/O.sgi/Makefile)
	preventing program crashes if a geomview command isn't completed
		before end-of-file (e.g. missing ')');
		(src/lib/lisp/lisp.c, src/bin/geomview/common/comm.c);
	making keyboard appearance controls ("ae", etc.) operate on the same
		settings as the Appearance control panel
		(src/bin/geomview/common/event.c);
	fixes for configuration bugs which caused geomview to look in the
		wrong place for external modules ($geomroot/bin/sgi/sgi
		rather than $geomroot/bin/sgi), so that $geomroot/bin/sgi
		had to be in your search path to run the standard modules;
		also the eucsyms module would not find its data files
		(top-level "config", "Makefile"; new directory src/config;
		src/bin/{geomview/common/main.c,eucsyms/*.c,hinge/*.c}).
