[CentOS] Constant screen flicker with Firefox browser

Hi Guys,

I'm facing this issue: https://bugs.centos.org/view.php?id=8482

It came after upgrading to 7.1 and only Firefox is affected, Chrome is
working.

What I've tried so far:

- Tried NVIDIA drivers 340.65, 346.59 and 346.72
- Upgraded Firefox to 38
- Tried Safe more / Refresh Firefox
- Tried to turn HW accel. off in Firefox

None of these has helped to eliminate the issue.

Do you know how to work this around?

Many thanks,
László
