I'm getting this as well when Render Cache is set to User, except it happens on some Fusion titles (not all) and not all the time, but when it does it's black straight away and in the Inspector, under 'Fusion' there's nothing there. Setting render cache to the above formats didn't help, but if I either select the clip and enter the Fusion tab, or else add an edit to the clip, it would come back to life - though in the case of adding an edit, only the part of the clip after the edit would work, the part before would still be black.
