OK, I also opened a bug report there:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851120
and I'll send a reply there linking to this discussion.
Could you add your own feedback there about what is expected to maximize
the chances that the display appears correctly on first boot into a
freshly built stretch system? Or does it only depend on the patching of
Virtualbox and there is nothing that could be done in xorg or wayland to
work around this seamlessly?
In those cases where the display doesn't work, is there anything that
can be done to give more meaningful feedback? The flashing screen isn't
great.

Should those links go into bug reports against the relevant packages so
this can be followed through?
