Basically sometimes when I open up amarok the context view pane shows up weird and not full, then I "restore" and "maximize" it or vice-versa and it turns out ok.
Steps to Reproduce:
1. Open up amarok
2. Try to do it in a non full screen startup
3. Try to do it in a full screen startup
This was solved after the beta release, see commit http://commits.kde.org/amarok/a0f4288e0b952830d38151264c0a8b042e32d8a4
