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:
List of printers expands and shrinks vertically when list of printers is being updated. This is caused by showing of Supply bar by default even if it is hid almost immediately.


Version-Release number of selected component (if applicable):
control-center-3.26.2-2.el7.x86_64


How reproducible:
Always


Steps to Reproduce:
1. have some printers installed (there must be at least one without supply info (e.g. a newly installed one))
2. rename one of them


Actual results:
printers list expands and shrinks immediately


Expected results:
printers list stands still


Additional info:
https://bugzilla.gnome.org/show_bug.cgi?id=790667

you can see also some horizontal shrinking/expansion but I could not reproduce it in RHEL 7 now:
 - https://bugzilla.gnome.org/show_bug.cgi?id=790663
 - please report it to us if you see such behaviour

I can confirm there is no strange behavior within the printer settings. I tried the reproducers along with a few more menu items/settings changes and the window(s) stayed still.
