The majority of cases we get generally occurs from running over the DP-DVI dongle. But I've also seen cases(notably my computer) where the DVI->DVI port also displays the same issues.
I've reseeded the graphics card, ram, etc find it clears up some of the issues. Sometimes restarting X or the computer may cause the problem to go away. After the initial first few dots appear on the screen this will progressively get worse over time. On a few computers running KVM with windows, you are able to switch back into windows and have no display issues at all.
Unfortunately I am unable to fail a working computer into this state.
I've also attached my latest gz.gif nvidia-bug-report.log.gz (34.3 KB) , which is running 190.42 . I've seen this occur on 195.36.15
