This looks fine, so far.

Was this printed immediately after you switched to frame 1 (on the Emacs
that has two frames)?  Or did you give the focus back to the other Emacs
(the one with a single frame) afterwards?

If the former is the case, could you please in addition to the earlier
instrumentation also instrument xi_focus_handle_for_device like such:

    case XI_FocusIn:
      device->focus_frame = mentioned_frame;
      device->focus_frame_time = event->time;

      fprintf (stderr, "XI_FocusIn\n"); <== add instrumentation here
      break;

    case XI_FocusOut:
      device->focus_frame = NULL;

      fprintf (stderr, "XI_FocusOut\n"); <== here
      break;

    case XI_Enter:
      if (!event->focus)
        break;

      if (device->use == XIMasterPointer)
        device = xi_device_from_id (dpyinfo, device->attachment);

      if (!device)
        break;

      device->focus_implicit_frame = mentioned_frame;
      device->focus_implicit_time = event->time;
      fprintf (stderr, "XI_Enter\n"); <=== here
      break;

    case XI_Leave:
      if (!event->focus)
        break;

      if (device->use == XIMasterPointer)
        device = xi_device_from_id (dpyinfo, device->attachment);

      if (!device)
        break;

      device->focus_implicit_frame = NULL;
      fprintf (stderr, "XI_Leave\n"); <=== and here
      break;

and show what is printed in the second Emacs (with a single frame) once
it starts to blink despite not being focused?

Thanks.
