As David pointed out, vertical-motion does that for a good reason:
fontification can well change the pixel size of the glyphs that Emacs
needs to display.
I think jit-lock-defer-time _is_ the way to avoid the slowness if you
are willing to see the text unfontified for a fraction of a second.
IIRC, Stefan introduced that option to provide functionality similar
to now-obsolete lazy-lock.
