Description Justin King 2015-10-10 15:57:56 EDT
Description of problem:

This problem is only reproducible when using the proprietary NVIDIA drivers and OpenGL rendering. It is especially apparent when using Firefox and other accelerated applications.

The problem is resolved by applying the following patches, in order as they appear, to mutter and bumping the release. I successfully did this with the RHEL 7.2 beta. 


These commits landed in the mutter 3.14 branch on 2015-08-13 in response to a severe issue with rendering discussed here:


The issue essentially causes redraws to only complete partially. From what I saw this was due to a race condition caused by using proprietary drivers where XSync is not sufficient enough. The proprietary drivers are necessary when using Quadro graphics cards or CUDA.

The only workaround is to force clutter into continuous redrawing which is far from ideal.

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


How reproducible:


Steps to Reproduce:
1. Install recent version of the NVIDIA graphics drivers for Linux.
2. Reboot.
3. Open a decent amount of tabs in Firefox and browse casually.

Actual results:

Partial redraws causing flashes and other graphical artifacts.

Expected results:

Properly redrawn graphics.

This should be included in mutter versions >= 3.14.4-11
