Interface gone white

I'm running Win 8 with Norton 360. After a Windows update, I launched 360 and there was a patch available. After that was all updated and restarted I went back into 360 and the background colour has switched from black to white. Even the grey circles are still visibale as part of the background image/style.

 

I can still see all the box icons and select all the tabs etc., I've even run a scan succesfully. Is this something to be concerned about or is it just superficial?

 

Thanks in advance!
