It seems you need to enclose non-printing characters in \[\] on bash
and %{%} on zsh.
So for bash: PS1="\[\$(dirbg)\] \u \w $ "
For zsh you have to setopt promptsubst in order to substiture \$(cmd), so:
setopt promptsubst
PS1="%{\$(dirbg)%}%n %~ $ "
Voilà. It works on urxvt and xterm, for the rest YMMV.
