Air for Android video object displays on orientation change

I have an Android app that plays a video using the normal video object, ie:

var nc:NetConnection = new NetConnection();

nc.connect(null);

stream = new NetStream(nc);

stream.client = this ;

stream.addEventListener(NetStatusEvent.NET_STATUS, statusHandlerx);

softwareVideo = new Video(640, 480);

softwareVideo.x = 0;

softwareVideo.y = 0;

addChild(softwareVideo);

When the video is playing if there is an orientation change, before the screen adjusts,  you can see a full screen version of the video behind the 640x480 in the area of the screen that adjusted yet.  So if the video is in portrait and the orientation is switched to landscape, in the right befow the stage adjusts to landcape you can see the right part of a fullscreen version of the video.

Also when I remove the video object you can still see the last frame of the video in that area.

HELP.  Is this a bug?
