Fixed In Version: virt-viewer-0.5.6-8.el6_5.1 Doc Type: Bug Fix
Doc Text:
Prior to this update, SPICE determined the scaling of windows incorrectly by using the original desktop size instead of the host screen size. As a consequence, when a guest window was open in SPICE, the screen could, under certain circumstances, become blurry. With this update, the guest window scaling has been fixed and this problem no longer occurs.

I can reproduce this now:
virt-viewer-0.5.6-9.el6_5.x86_64

my physical monitor's resolution is 1680*1050
host and vm are both rhel6u5

Steps:
1. start a spice rhel guest
2. # virt-viewer $vm --debug --spice-debug
3. maximize the guest, and open the display preferences of the guest.
4. keep change(increasing) the client panel size

Result:
I keep increasing the panel size, When the guest resolution is 1680*839, the display is blurry.
