Top panel will only open every other swipe
The top panel takes two swipes to open. This seems to be consistent behavior. In addition if you open an application such as system settings and swipe down on the panel the first time, you'll notice the header of the application (in my case system settings) will turn a different color to indicate it's not in focus. Then when you swipe a second time while it's still out of focus, the top panel will not come down.
