Hi,

Yes indeed.

You can find it here:

However, these VT sequences definitely won't work in other terminals. But the general case should be clear. Only VT sequences are written to the terminal that do not generate any text.

Best regards,

Christian Parpart.

Oh, I think I know what this is about. This is almost certainly not a
bug in zsh.

Do you print something to the terminal in precmd? If you can post the
code of the precmd hook, it would help.
