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:
Rendering artefacts visible in a number of applications, including firefox, when used with nvidia drivers due to a bug in clutter.

1.14.4-12.el7_1.1
How reproducible:
On every machine with nvidia graphics I've tested
Steps to Reproduce:
1. Start firefox
2. Open a complex web page
3. Move the mouse around
Actual results:
Tearing and visual artefacts
Expected results:
Normal rendering
Additional info:
This has already been reported against Fedora, and was fixed in later versions of clutter. Bugzilla #1081625 references the simple patch that fixes the issue.
https://git.gnome.org/browse/clutter/commit/?h=clutter-1.16&id=6665f47d66a871b6e1a5f4200282f42da043a0e8
This patch has been tested as applied the EL7 SRPM and is confirmed as working. The fault is definitely with clutter and not with nvidia.
