I, too, was a bit confused at the frozen arrow in the beginning, until I realized it was just the loading indicator used when animations are disabled (they could probably improve that one). It is the one place where some sort of movement might still be appropriate.

Anyway, I recently disabled this feature due to it breaking the scroll behaviour in Play Store. Ironically the only app (I've noticed) that uses animation for scrolling in a way that makes this accessibility feature break it, making it a very jarring experience.

Instead, I went into developer tools and scaled all animations down to 0.5x. This at least makes all the annoying transitions bearable. I think this setting should also be exposed under accessibility settings.
