If invoking `redisplay' fixes the problem, it means some display
optimization is misfiring. But there are quite a few of those
optimizations, so without a reproducible test case, it's really hard
to say where to look.

I agree with Antoine: if you can reliably reproduce this with your
~/..emacs, bisect it to find the minimal customizations necessary to
reproduce the problem, then post that information here.
