RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.	Story Points:	---

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.
