FWIW, Breeze shadows can now be turned off entirely (System Settings > Application Style > Window Decorations > Breeze > Click on the little Settings button in the corner > Shadows > Size: None), so the only thing this really adds is opaque backgrounds. Not sure it's worth it IMHO. Maybe instead we should let people turn it off in Breeze without modifications.
