You should definitely submit a bug to Apple. You can reference FB13444225,
which is my report of the bug that causes ScreenSaverViews to not be removed
after the screensaver stops, and they keep running after the screensaver starts
up again, so they keep multiplying.

Yes, Apple broke legacy screensavers when multiple monitors are present, even
some of their own screensavers. We just have to wait for them to fix it. It's
been reported, and I've heard that they are aware.
