List glitches when scrolling quickly

On mobile and desktop, when there is many events in the list, scrolling quickly through it will occasionally display the bottom or top of the list depending on which direction is scrolled.

This can be 'fixed' by changing the min and max buffer sizes. This will change how many pixels are rendered in the scroll-viewport. Increasing these will decrease how often the glitch occurs, but it will affect how quickly the events are to load into the list.
