Remove Animations with "Safe Display" Enabled

- [ ] The only animations that I still see are the active scrolling when scrolling the deck list, which I do often enough that it is annoying,

If at all possible, when animations are disabled, a swipe up or down on the deck list should probably move the list a proportionate amount without actually showing the scrolling animation.
