[gnu.emacs.bug] Garbelled screen

STANKE@sdr.slb.com ("Fred E., SDR Ultrasonics, 431-5469", 203) (07/27/89)

I am running

GNU EMACS 18.52.5 Thu May 11 1989

on

VAX/VMS A5.1-1 running on a VAX8600.

Frequently, when the screen needs to be refreshed as in paging, the screen
becomes garbelled, characters and blocks of characters are missing.  This
did not happen with a previous version of GNU EMACS.  

Any suggestions?

Thanks very much.
