Position of Game Center dashboard

When opening the Game Center dashboard via the Access Point, the Game Center dashboard appears BEHIND any content in the window with z depth (default type not volumetric). It obscures the dashboard and this makes it unusable.

Alerts have the same placement.

The new defaultWindowPlacement would probably suffice, but I don't think there's a way to apply that to the Game Center window.

What to do?

Thanks.
