Draw effects: features vs entire layer in QGIS

Draw effects in QGIS are amazing because you can style a layer in some really nice ways. But if you have a layer comprised of multiple features (e.g. polygons) it is easy to get it wrong so that's what I discuss in this video.
Have a look anyway because it's very useful for things like drop shadows.
