Thanks for testing these too. Are you using spice or vnc? In any case it
would be best if you would report these bugs upstream at either

vnc:

    https://bugzilla.gnome.org/buglist.cgi?quicksearch=product%3A%22gtk-vnc%22%20

or spice:

    https://bugs.freedesktop.org/buglist.cgi?component=spice-gtk&list_id=281013&product=Spice&resolution=---

I can play the MITM but I think this would only slow down things. I'd be
great to keep this bug in cc:.
Cheers,
