If you have RPS1 set to something, I can explain what happens: The
problem is that urxvt reflows lines when you resize the terminal,
which can add a line, then zsh redraws it too, which keeps half of the
old line. I have no idea why it happens with a multiline prompt
though; it seems zsh doesn't output spaces to the end of the first
line. You get a quite fun effect if you setopt promptcr promptsp and
do echo -n foo, then resize (wider or narrower).
