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 of problem:
When running our desktop automation tests under Wayland - via python3 - the wl_display will sometime attempt to delete the same display twice and the communication between client(python3) and compositor will end with message: Gdk-Message: 13:44:53.888: Error 22 (Invalid argument) dispatching to Wayland display.

Not 100% but eventually will appear.

Steps to Reproduce:
Do not have step by step reproducer. See attachment.

Additional info:
Issue filed upstream as it can be reproduced on Fedora 35 also https://gitlab.gnome.org/GNOME/mutter/-/issues/1797

I am no longer able to reproduce the issue with the fix provided by Olivier in https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/77 , he made a scratch build for rhel-9 which I run on multiple machines and multiple test suites and not a single occurrence of this issue was found.
