Description John Hodrien 2015-09-17 12:11:48 UTC

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

Version-Release number of selected component (if applicable):
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.

Comment 2 Ashish Shah 2015-10-22 09:38:55 UTC

Patch looks available in clutter-1.20.0-4.el7 under rhel7.2 beta

Comment 4 Owen Taylor 2017-01-10 19:16:58 UTC

As noted in comment 2, this was resolved in RHEL-7.2.
