Please make a separate bug-report about this. The region highlighting has been moved to Elisp, and it seems that follow-mode's highlighting code seems to interact poorly with the new behavior. But the good news is that follow-mode could use the new Elisp highlighting to "do it right" (no need to use hacks to try and coerce the redisplay to highlight the region over more than one window).
