   Does anyone else see this redisplay bug?  I do M-x info, visit the Emacs
   manual, scroll down 2 pages.  When I now scroll back 2 pages the display
   is completely messed up.

This seems related to the header line.

After: 

(setq Info-use-header-line nil)

the problem disappears.

Sincerely,

Luc.
