SUOverlayEnable calls are not reflected in UI

[noelwarren]

Calls to SUOverlayEnable seem to work on a functional level

if set to true, SUOverlayCreateInfo::start is called, as are frame related functions
if set to false, SUOverlayCreateInfo::stop is called, and frame related functions stop getting called

But the visual representation of the overlay does not update accordingly.
(After a call to SUOverlayEnable(overlay, true))

Note: the same is not true of the ruby overlay api
