[Impact]

Users of Nvidia gfx using the proprietary driver may see screen
corruption during certain operations.

[Test Case]

* Install an Nvidia graphics adapter and the proprietary driver.
* Observe the graphics corrupt.
* Install the version of Compiz with this fix.
* Observe corruption is gone.

[Regression Potential]

The patch for this was provided by Nvidia.  There could be some corner
cases users hit that may cause other issues.  That said, enough testing
has been done to confidently say that the gains provided by this fix far
outweigh any corner cases.

Original Description:

== Proposed compiz-fusion-plugins-main patch ==
See comment 234 by Anders Kaseorg and attached compiz-fusion-plugins-main_0.8.2-0ubuntu2.debdiff.

== Original report ==
Binary package hint: compiz

I'm using latest compiz on intrepid.

Since jockey-gtk does not work on my box (I already filed a bug), I
manually installed nvidia-glx-177 and added the "driver → nvidia" line
to xorg.conf.

Now I seem to be having some screen refresh problems when using compiz:
parts of the screen are refreshed, but others aren't. That means
nautilus doesn't show files or folders until I move the cursor over
them, firefox doesn't show webpages properly until I scroll down, and so
on.

Please, tell me if there is any additional info I can provide to find
out the cause.
