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.

Description Bill Sanford 2013-02-05 21:35:13 UTC 
Description of problem:
When the two displays of a remote-viewer are in full-screen in a multi-monitor RHEL setup and you change the resolution of one display, then leave full-screen, the displays will flicker heavily (with random garbage in the windows) while trying to re-size the resolution.

Version-Release number of selected component (if applicable):
RHEL6.4-20130123.3 64-bit host
RHEL6.4-20130123.3 32-bit guest

How reproducible:
75%

Steps to Reproduce:
1. Install RHEL 6.4 with a two monitor setup and install RHEL 6.4 VM.
2. Start the server (below).
3. Start remote-viewer spice://127.0.0.1?port=5900
4. Add a second display through the remote viewer and switch to full-screen.
5. Change the resolution of one monitor to 1024x768.
6. Exit full-screen.
  
Actual results:
Displays are caught in a flickering loop.

Expected results:
Displays come out of full-screen.

Additional info:

I started the spice-server with the following command-line:

qemu-kvm -m 1024 -spice port=5900,disable-ticketing -vga qxl -global qxl-vga.vram_size=67108864 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x8 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 <image>
Comment 1 Hans de Goede 2013-02-06 16:47:44 UTC 
I've tried to reproduce this and failed, but this bit of the description:

Actual results:
Displays are caught in a flickering loop.

Sound exactly like bug 894421, just triggered in a different way, so I'm marking this one as a duplicate of that.
