Obvious experiment: set the superview to be opaque.
Indeed. Already tried it (right after posting), and it makes no
difference. I'd try rearranging the view hierarchy to test the
effects of that, but that isn't trivial, because it is arranged
programmatically, so I'm hoping someone has already explored this...
More generally, I am interested in knowing how this mechanism works,
beyond just fixing my immediate problem, so I hope somebody can
comment on that more generally. And whether there is any way to
affect it, beyond my immediate case. I find nothing in the docs about
it.
