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 Rob Garth 2008-10-28 11:12:16 UTC
Created attachment 321692 [details]
Patch to fix the redraw problem

Description of problem:
Running QT or GTK apps results in fonts, icons and other details either failing to draw or rendering with incorrect colours. Running Xdmx with -norender fixes the problem, but it is very slow and an unacceptable solution.

How reproducible: Every time


Steps to Reproduce:
1. Start xinit on client nodes
2. startx `which gnome-session` -- Xdmx :1 -display host1:0 -display host2:0 +xinerama
3. Many aspects of the windows fail to render.  Firefox has problems too. Happens with KDE and the same apps run under twm.
  
Additional info:
I have included a patch which can be applied to the SRPM and fixes the problem.

Comment 1 Adam Jackson 2013-11-05 18:55:04 UTC
The patch isn't correct, but I'm pretty sure the equivalent problem is still present in RHEL7.

Comment 4 Adam Jackson 2014-06-12 17:22:55 UTC
After some digging, it looks like this is the same issue as:

https://bugs.freedesktop.org/show_bug.cgi?id=7555

Which was fixed upstream in the xserver 1.2 branch.  Therefore I believe this issue is resolved in all RHEL6 and RHEL7 X servers.
