--- Comment #9 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
I suspect the cursor getting stuck is caused by the DDB/WM update cancelling
the already armed cursor disable. And later we don't rearm the cursor disable
before the pipe gets shut down.

I was trying to come up with a better way to do the plane/ddb/wm updates (for
bug #104975). It might be worth a shot here as well:
