after commit 2789bb0813376caf59da7f80b83c3db28c0fc370, flipping between buffers with color syntax (but two diff syntaxes) enabled results in lots of flashing.

for example, download these two files:
https://gitweb.gentoo.org/repo/gentoo.git/tree/app-portage/eclass-manpages/files/eclass-to-manpage.awk
https://gitweb.gentoo.org/repo/gentoo.git/tree/app-portage/eclass-manpages/files/eclass-to-manpage.sh

then open them up like so:
$ nano -F eclass-to-manpage.{awk,sh}
i've cleared my ~/.nanorc and am using the default /etc/nanorc only that ships with nano.

then hold down M-> to flip between the buffers quickly.  when going from the awk to the shell, you can see the blue comments briefly flash green before the content is cleared and the shell code is rendered.  i picked these examples because they're easier to see, but the repaint errors seem to exist with all formats.
