BTW, I noticed that while this flicker is definitely happening on my
machine at work, my home machine doesn't show it!  Since my home
machine is slower, has a crappy video card, and runs an ancient version
of X, I don't think it's just less visible or anything.

The odd things is I'm using _exactly_ the same emacs source code for
both (basically CVS HEAD with a few probably-not-related tweaks), the
same configuration, and mostly the same OS (debian, but home is testing
and work is unstable).  I've done a `make clean; make' to flush out
bogons, and I'm using `emacs -q' to test it.  I'm completely confused as
to why it's happening.

[Fonts?  gcc version?  I'm running XFree86 3.x at home and 4.x at work,
so maybe the newer version somehow sending odd events or something...]

Unfortunately the machine that's displaying the problem is my work
machine, whereas my emacs debugging time is at home... :-(
