Actually I don't think we have a good solution for this yet. When it was last discussed (Den Haag?) and some times before I suggested we should just do shadow updates when the input area changes (or some other client-initiated call). What we shouldn't do is try to generate a new shaped shadow on every frame, unless there's reason to believe the shape has changed.
