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.

Red Hat Product Errata RHBA-2015:2216 0 normal SHIPPED_LIVE gnome compositor stack bug fix and enhancement update 2015-11-19 08:26:34 UTC

Description Rui Matos 2015-10-26 09:55:19 UTC
When unplugging monitors, mutter emits this:

Oct 26 10:49:26 dhcp-4-136.brq.redhat.com gnome-session[1953]: (gnome-shell:3073): mutter-CRITICAL **: meta_screen_get_monitor_geometry: assertion 'monitor >= 0 && monitor < screen->n_monitor_infos' failed


This is due to the desktop window (i.e. the nautilus window containing desktop icons in the classic session) being special cased when moving windows due to the monitor unplugging. The special case is required but it's implemented incorrectly, leaving that window associated with invalid monitor data.

This might be a cause for crashes later on, though I didn't actually hit a crash because of it.
