Timeline Gallery and split screen- bugs?

Hi
Has any one else come across these issues...?
1. The Timeline Gallery thumbnails are 'zoomed-in' until I go to the timeline in question and scroll through the clip thumbnails, then the gallery stills come good.
2. Split Screen>Selected Album does nothing.
