I've noticed this too with the control strip. Eventually the whole thing goes black except for maybe one "button" worth of area, like it missed a redraw or something. Tapping on a black area where you know a button is will redraw that button but you have to close and reopen the lid to get the whole thing normal again.
It also had a kernel panic displayed on the control strip (which is a separate OS) the moment I turned it on for the first time. It was kinda hilarious, the panic text was written sideways on the control strip, and since it's so thin there was a line break every 4-5 characters.
