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.
