Is this reproducible, e.g., with that blog post?  I've seen in the
past redisplay problem with images, but they would disappear in a
fresh session of Emacs, even if I made exactly the same gestures as
the ones which reproduce the problem in a long-running session.  Do
you have the same experience?

When you do have Emacs built with -DGLYPH_DEBUG=1, and this happens,
invoke "M-x trace-redisplay RET", and tell what it prints to stderr
when you do whatever is needed to reproduce the problem.
