Regarding the bug itself... This does sound like either a driver
problem or a problem with the hardware itself. If the latter, then the
issue would show up in windows as well, which no one has mentioned so
maybe we can assume it isn't.
>From the spacing and pattern of the dots it looks like graphics memory
writing failure. Like, the driver wasn't able to keep up with the data
stream and skipped writing a pixel. This type of problem often will
just "go away" after updating to a better performing software stack
(either kernel or -nvidia or both). Thus, in this case having it re-
tested against natty really is necessary as a first step.
If it does occur with the nvidia in natty, then this bug should be moved
from 'nvidia-graphics-drivers-180' to 'nvidia-graphics-drivers' and
tagged 'nvidia'. If you run "apport-collect 421048" on natty I think
that should do the trick, but am not sure. From there, Canonical can
flag the issue for NVIDIA to investigate.
** Changed in: nvidia-graphics-drivers-180 (Ubuntu)
