Sometimes the video item or viewfinder is shown not taking up the whole of the space of the graphicsvideoitem - the video/viewfinder appears in only part of the graphicsvideoitem, and the remainder of the item appears transparent.

Can be reproduced by using videographicsitem.sis or viewfindergraphicsitem.sis test applications, and rotating whilst video is playing or viewfinder is showing. Test applications can be found in http://bugreports.qt.nokia.com/secure/attachment/20383/multimediakit.zip, and it can be reproduced with this video clip
