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.

VNC desktop with wrong colours
Description of problem:
Colours of VNC desktop in vncviewer on ppc64 are wrong and there is also some repainting when moving window or select/highlight with mouse.
Version-Release number of selected component (if applicable):
tigervnc-1.8.0-9.el7.ppc64
How reproducible:
always
Steps to Reproduce:
1. $ vncserver :1
2. $ vncviewer :1
Actual results:
colours of desktop are wrong
Expected results:
colours of desktop should be correct
Additional info:
It is very probably endianness problem. Tested with vncserver running on ppc64 and x86_64, vncviewer on ppc64 had always wrong colours.
Via Vinagre colours of VNC desktop are correct.
Do you have chance to test on RHEL 7.5 with older Xserver and tigervnc? I would like to know whether it's a regression in RHEL 7.6 or whether this has been a problem for a long time.
Desktop colours now looks correct with tigervnc-1.8.0-10.el7.ppc64. Switching to verified.
(However there remains small issue, that popup with "Press F8 to open the context menu" is blue tinted. Filed that to bug 1618777.)
