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.

Changing this to gnome-control-center but tbh, I suspect g-c-c might be using XRandr here so that might be expected behavior. I'll let the g-c-c maintainers decide what to do with the bug though

gnome-control-center doesn't use RANDR, it always uses the mutter D-Bus API. I can reproduce something similar to this with RHEL-9.2.0 (but not RHEL-9.0.0). What appears here is that clicking "Apply" makes gnome-shell apply the RANDR configuration (e.g. flipped), and continues to render like normal (confirmed with gdb breaking in cogl_onscreen_swap_region, as well as taking a screenshot which shows the confirmation dialog), but the content shown on screen doesn't update. It looks like it was applied, but if you e.g. run 'glxgears' somewhere on screen, it'll freeze, and if you press 'Esc' it will effectively activate the Restore button and things will go back to the configuration before pressing Apply.

Thus, this is likely a bug in the X server, the kernel or spice-vdagent.

Moving to spice-vdagent for further investigation.
