Anti-alias shadow maps used on Spotlights. It works by implementing an old school technique of spinning (Spinning Light Trick) a light across a frame time in order to offset sample positions. It helps reduce glitches and improves overall image quality. Apply it to a Spotlight in its Motion Options, enable motion blur and see what happens when you render.
