I did a little more testing today. I did see the "Waiting for display ...2" message whenever
I started the remote-viewer with 1 monitor and tried to add a second. It happened both
with and without the patch. If I added the second monitor, closed the viewer and
re-opened it, the second monitor will display just fine.
The good news is that when the this patch is paired with the monitor config qxl patch,
https://bugzilla.redhat.com/show_bug.cgi?id=1202419, I don't see the problem at all.
