Hey there. Found one bug: when you set 5 shortcuts to the circle (the one which is shown when you swipe up from the Home button) and turn the phone to the landscape, 1 and 5 shortcuts are mispositioned and cover part of the Back and Recent buttons (on the screenshot you can see that they cover about the 1/3 of the button). The problem is, when you just try to press the Back or Recents button, it thinks that the circle is opened (but it's not, of course) and it reacts like you have pressed 1 or 5 shortcut.
In my case, when I try to press Back, phone brings me to Phone etc.
Hope I described it clear enough
