Summer Update - All Shows Trapped in Right Hand Corner

Received the Summer Update on my Roamio. Now all shows are only displayed in the top right hand corner like the preview window.



If I press live tv only displays in the top right hand corner.



If I go to now playing it and play a previously recorded show it goes to the top right hand corner.



Have tried rebooting and power cycling the Roamio but nothing has helped.



Anyone else seeing this?
