Here is the original topic from the nvnews: http://www.nvnews.net/vbulletin/showthread.php?t=175647
The summary of the topic:
The issue is quite old, but happens with the latest drivers.
It happens on 10 bit displays only as far as I can tell.
Playing with the dithering settings only delays the problem.
It doesn’t happen with 290.10 or older, but these drivers cannot be installed in a “modern” distro (centos 6 updated to latest).
NVIDIA internal Bug ID: 972439 to track this issue
Any chance for a fix to this issue?
I’m available to test alpha/beta drivers if there is need for it.
