Description CongDong 2014-06-19 11:00:44 UTC 
Description of problem:
remote-viewer only show one display if connect windows 7 guest on a 4 monitors machine, if try 2 or 3 times, it works.

Version-Release number of selected component (if applicable):
virt-viewer-0.6.0-7.el6.x86_64
spice-server-0.12.4-9.el6.x86_64
spice-gtk-python-0.22-4.el6.x86_64
spice-vdagent-0.14.0-3.el6_5.x86_64
spice-gtk-0.22-4.el6.x86_64
spice-xpi-2.7-24.el6.x86_64
spice-glib-0.22-4.el6.x86_64
virtio-win-1.6.8-4.el6

How reproducible:
100%

Steps to Reproduce:
1. Install a win7 guest on a 4 monitors machine, install spice agent and qxl dirver in it.
2. configure it with only one display first
# virt-viewer $vm
make sure only one display comes out
3. close virt-viewer, use remote-viewer connect the guest
# remote-viewer spice://$ip/$port --full-screen --debug

Actual results:
Stpe3, only two displays comes out with fullscreen,
but seems 4 displays are ok form log.
# cat $log
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 0 0x1a70840
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 1 0x1a70e40
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 2 0x1ab9e10
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 3 0x1ae1240
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 0: 1
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 1: 1
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 3: 1
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 2: 1
...

when I connect the guest second time, 3 displays comes out
when I connect it third time, 4 displays comes out.

Expected results:
4 displays should come out in fullscreen mode when I connect it first time

This is unlikely a client bug, auto-conf is correct:

Comment 4 Marc-Andre Lureau 2014-06-19 13:14:44 UTC 
I can reproduce, using upstream spice-guest-tools-0.74.exe on rhevm 3.4

However, I couldn't reproduce on f20 with qxl 6.1.0.10018 and spice agent 0.7.2.7-1b0e

actually, result is random, looks like something racy, ok moving component

CongDong, no need for logs, it can be reproduced.

thanks

Comment 7 Marc-Andre Lureau 2014-06-19 16:03:14 UTC 
iirc, this commit was solving this issue, and was later reverted because I didn't manage to find reproducer:

commit 67c1bcf49367d1726033b298a8ab016b4e22cf23
Author: Marc-André Lureau <marcandre.lureau>
Date:   Sat Mar 16 00:55:15 2013 +0100

    Refresh monitor config only when needed
    
    Somehow wnd_proc()->get_display() may be reentered during ChangeDisplaySettings
