OS 3.1 Coverflow Bug?

I don't know if anyone else has this issue, but when I'm playing music on my iPod touch (3G, 3.1OS) and I go from the vertical, text menus to coverflow,then play a song in coverflow and QUICKLY turn my ipod vertical (like the exact moment i select the song), the screen remains in horizontal mode in coverflow, yet if I do the same thing but from the Now Playing screen I have no problem. I've also noticed that if it doesn't revert to vertical mode and I turn it back and forth again, it will work, but the album art will be slightly moved to the top of the screen, blobking some of the artwork. Anyone else have this problem? What is causing it?
