CDThumbnail not shown in newest xbmc V12 builds

Hello! Have an problem in the fullscreen visulisation. After the change of the intern databases from xbmc versions from 1. juny on cd covers are shown in the main menuscreen. When I open the fullscreen visulisation the first track the cdthumbnail is shown but for the next tracks the thumbnail aren't shown anymore until I step back to menu screen, then after forward one or two tracks thumbnail is showing again but in fullscreen again only one track.

My database is corecct tagged and in the log no error shows up. Can you look where the problem is ronnie?

Thx
