Isn't it strange that only some people see these problems, while
others (the majority?) are very happy with double-buffering?  Could it
be that the problems are triggered by some specific system
configurations or Emacs build-time features?  If so, we could perhaps
turn it off only for those configurations, because people who are
happy with this are extremely happy, and will probably be disappointed
if we just turn it off globally.
