So, I did a quick test where I used an un-modified spice-server and the
following diff to virt-viewer:
===================
diff --git a/src/virt-viewer-session.c b/src/virt-viewer-session.c
index 131a500..5f47d09 100644

====================
This is basically what you suggest. While we're in auto-conf mode, it never
sends down monitor config changes, but it does respond to display updates from
the server. When the user exits fullscreen mode, it resumes auto-resize and
sends new monitor config messages to the server. It improved the situation, but
didn't fix it. Before applying this patch, when I started virt-viewer in
--full-screen mode, the extra display was left enabled about 25-50% of the
time. After this patch, it happens only about 10% of the time.
But it also seems to introduce a regression that I haven't investigated yet:
when things work properly (e.g. only a single fullscreen display is shown) and
I follow these steps:
- exit fullscreen
- enable a second display (View > Displays > Display 2)
The second window appears, but it simply displays "Waiting for display 2..."
forever. The display only shows starts working after you resize one of the
windows.
