If sourcetree is started with a maximised window from the previous session, the "Jump to" button and the scrollbar of the history on the right hand side seem to be cut off. In addition, the top bar of the app (file, edit, view etc) is also cut off, as if the screen was x pixels larger.

Restoring down and maximizing the window again seems to remove that issue. But it reappears after every restart. This seems to have been introduced with the latest beta.
