I'm on the latest beta and I've noticed a few crazy things with the UI this beta.
When I have a few apps open and try and switch between them the entire UI will freeze for a brief moment before finally completing the action. This freeze can be 2 seconds to 10 seconds. From what I can tell the lag varies on how RAM the apps use.
Second thing is sometimes when doing splitview Chrome will simply vanish. This might be more of a Google problem. But I didn't notice it last beta.
