I installed a change along these lines. A buffer that sets the new
variable make-window-start-visible non-nil should force redisplay to
reject a window-start point that is in invisible text or is covered by
a "replacing" 'display' property (which also makes window-start
invisible), and choose a different starting point.
Please test.
