No, I have seen the black background, I assumed that was due to low memory. In this case, the window doesn't show up, it is invisible. The window is there however, as onWindowFocusedChanged occurs, and if you due something to force it to show.. such as pull down the notification bar, or hold the home key, then it is visible again.
This issue appears to be a broader theme bug, as I was able to reproduce the same thing with a theme which only turns off the window title. I submitted a bug on this here: http://code.google.com/p/android/issues/detail?id=2910 Also, just to note, this is 1.5r1.
