Glitchy animation when loading in several chat messages

Steps to Reproduce:

• join streambot
• all chat messages come in and animate weirdly

A solution to help reduce this jitter would be to hide the chat tableview entirely while chats are loading, and start a loading spinner. Also, setup a 1 second (or something) timer. In the method where a new chat comes in, restart that timer, so that once there's no new data, the timers action method will fire, which hides the loader and shows the chats perfectly loaded without animation.
