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 Florian Müllner 2022-11-23 12:56:08 UTC 
+++ This bug was initially created as a clone of Bug #2138941 +++

Description of problem:
After installing and configuring the classification banner extension, it is observed that the top panel of the GDM login prompt and the classification banner overlaps. This behavior is not observed after logging into a user session.

Version-Release number of selected component (if applicable):
gnome-shell-extension-classification-banner-3.32.1-27.el8.noarch
Red Hat Enterprise Linux 8.6

How reproducible:
I was able to consistently reproduce.

Steps to Reproduce:
1. Configure classification banner per documentation.
2. Restart GDM or restart system.
3. Observe behavior.

Actual results:
Top bar/panel of GDM login prompt overlaps classification banner.

Expected results:
Top bar/panel of GDM login prompt does not overlap classification banner.

The issue is that the extension uses the work area for positioning, but gnome-shell skips setting it for the greeter.

I suspect that that's just an optimization - the main purpose of the work area is to determine the area that can be occupied by windows, and there are no windows on the login screen - and the issue can be addressed in gnome-shell itself. Otherwise I'll have to come up with a work around in the extension.

Done now upstream in https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2546.

Packages:
gnome-shell-40.10-4.el9
gnome-shell-extension-classification-banner-40.7-3.el9.noarch.rpm

There is no longer an overlap or conflict with the top bar of GDM and the classification banner using the above packages. See attached screenshot. I will say the off center "TOP SECRET" due to including the system info, but that's a topic for another bug.
