Bug Description
There is too much (inappropriate) shadow rendered for non-rectangular surfaces.
Test case:
$ mir_demo_
Expected:
Either a shaped shadow or none at all.
Observed:
In Unity8 there is a constant shadow over the background.
In mir_proving_server there is a line of shadow around the invisible border.
Both are wrong.

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.
