If I remember correctly, the hardware cursor on NV4E is very sensitive/buggy.

This commit in the nv driver from years ago might give you a lead:

Yes, the is the likely culprit.  However, we can't just stick a 1 second
sleep
in our cursor enable/disable function, that would be ridiculous.  I suspect the
hw bug is somewhat more specific than that.

I attempted to ask NVIDIA for information on the cause a long time ago..
However, as expected, apparently this is far too secret to possibly reveal.  I
don't have any of the effected hardware to tinker with it myself.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
