It doesn't seem to fix the garbled non-select completion.

This simpler solution seems to work for me:

zstyle -e ':completion:*' menu 'reply=(yes=$((LINES/2)) select)'
_vbe_half-lines() {
    LINES=$((LINES/2))
}
_vbe_full-lines() {
    # Force terminal query
    LINES=0
}
add-zsh-hook preexec _vbe_full-lines
add-zle-hook-widget line-init _vbe_half-lines

Its scope is wider than completion, but it doesn't seem to break
anything for me.
