Bug 124754

When the settings are changed to "Thousands of colors" the banding
goes away.  Reset to "Millions of colors" they re-appear.

Please file a bug report in the upstream X.Org bugzilla, and paste
the URL here, and we will track the issue in the upstream bugzilla.

Problems that occur using the "nv" video driver, require Nvidia's
assistance to fix, as the driver source code is obfuscated and
the open source community has no knowledge of the operation of
the Nvidia hardware to be able to debug/troubleshoot/fix the
driver, however the Nvidia driver maintainer (an Nvidia employee)
may provide fixes for problems they're made aware of in X.Org
bugzilla.

Once you've filed a bug in X.Org bugzilla, if you would like Red
Hat to track the problem there, please paste the URL in this bug
report and we will carbon copy on the upstream bug report and
review it from time to time.

Thanks in advance.

NO, this is using the stock xorg driver not the nv driver.

In regards to "upstream blah blah blah", please speak English, I don't
know what you're talking about.  ;-)

The stock xorg driver _is_ the "nv" driver.

"Upstream" means "the people who wrote this software".  Red Hat
ships a lot of software in the OS distribution, however Red Hat
did not write all of this software from scratch.  The X.Org
project is the official open source project which develops the
X.Org X11 X implementation.  In other words, "X.Org" is the
official "upstream" project for the X.Org X11 software.

The official X.Org website is at http://www.x.org, and the
software is hosted on the Freedesktop.org website at:
http://xorg.freedesktop.org

The official bug tracking database for the X.Org X11 software is
located on the freedesktop website at the following URL:

    http://bugs.freedesktop.org

To file a bug to the official software project, go to the above
URL, create a user account, log in, and then you can file a bug
report against the "xorg" component.  This is what I mean by
file a bug report upstream.

The reason you must do this, is because the only people who can
fix bugs in the "nv" driver, are people with knowledge of how the
Nvidia hardware operates, who have access to the specifications
of that hardware, and who understand the driver source code.

The only person with detailed knowledge of Nvidia's hardware,
with access to the specifications, and who hacks on the driver,
is the driver maintainer, and he doesn't read bug reports in
Red Hat bugzilla.  ;o)

Once you've filed a bug report in the X.Org bugzilla at the
above URL, paste your bug report URL here, and we will track
the issue upstream.  If a fix becomes available from Nvidia, we
can review it and consider including it in a future update, however
if no bug fix becomes available, there is nothing we can do
to fix the driver.

Thanks in advance, hope this clears up any confusion.

Take care,
TTYL

Since this bugzilla report was filed, there have been several major
updates to the X Window System, which may resolve this issue.  Users
who have experienced this problem are encouraged to upgrade to the
