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.

It's hardware independent, screenshots are from Quadro 2000 GPU.

First screenshot is is after changing resolution from 1400x1050 to 1600x900.
Second screenshot is after changing 1920x1080 to 1600x900.

on the problem set up, what's the output of

$ gconftool-2 -R /desktop/gnome/background

?

Comment 7 Ray Strode [halfline] 2014-06-24 14:45:29 UTC
when the problem happens, if you go to the background tab of the appearance capplet and change the style from "Fill screen" to "Tiled" and back to "Fill screen" does the problem go away?

If you select a different background, does the background update?

I have simpler reproducer for you. Connect external monitor and run: xrandr -o left

Comment 10 Ray Strode [halfline] 2014-06-25 19:46:34 UTC
if you run:

$ gconftool-2 --set /apps/nautilus/preferences/show_desktop --type boolean false

does your reproduce still work?

No, it's ok.

Comment 12 Ray Strode [halfline] 2014-06-26 13:56:26 UTC
okay sounds like maybe nautilus isn't listening for the "monitors-changed" signal or something along those lines.
