After connection to agent-less guest with 16b colour depth, initial screen is black and gets drawn on change only

spice-gtk-0.11-11.el6.x86_64
spice-server-0.10.1-10.el6.x86_64
qemu-kvm-0.12.1.2-2.295.el6.x86_64
windows xp guest
qxl 5.1.0.10012 (2011/10/05)

How reproducible:
always

Steps to Reproduce:
1. have and winxp guest, stop the vdagent if running
2. in display properties, switch the colour depth to 16
3. connect to the guest with spice-gtk-based client
  
Actual results:
guest screen is black till first change (redraw) such as clock change, monitor bar movement, drag area chooser movement, window movement or any other window part redraw

filed against spice-gtk because this doesn't occur with spicec

vdagent less use case has low priority

Comment 3 Christophe Fergeau 2012-09-18 14:07:41 UTC

I cannot reproduce this in f17 (spice-gtk-0.12-4.fc17/virt-viewer-0.5.3-1.fc17) nor with git master.

Reproduced easily according to instructions. Just did exactly what it says:

1. have and winxp guest, stop the vdagent if running
2. in display properties, switch the colour depth to 16
3. connect to the guest with spice-gtk-based client

With RHEL client:
$ rpm -qa | egrep "spice-gtk|virt-viewer"
spice-gtk-python-0.14-2.el6.x86_64
spice-gtk-0.14-2.el6.x86_64
virt-viewer-0.5.2-11.el6.x86_64
spice-gtk-tools-0.14-2.el6.x86_64

and WINXP as guest (with latest unsigned qxl even)

Comment 5 Christophe Fergeau 2012-10-11 15:12:37 UTC

This bug only happens when the qxl driver is used, not when the cirrus driver is used, that's why I could not reproduce initially.

Comment 6 David Blechter 2012-10-15 18:02:28 UTC

Out of time for 6.4, not a blocker, moving to 6.5

Comment 7 Marc-Andre Lureau 2012-10-16 11:11:25 UTC

Comment 9 Marc-Andre Lureau 2012-12-10 13:08:58 UTC

Fixed in spice-gtk-0.14-5.el6
