Enforce background fallback to be non-translucent

To avoid screen garbage or wallpaper shining through, the background
we use there for filling the whole needs to

a) Be non-translucent in all cases except if the window is translucent.
b) Don't infer it from the theme as it might be unexpected. Don't define
it in the theme, and use black if it's not defined.
