Open up Ristretto, and view an image. Make sure "Show Status Bar" under View is unchecked. Enter fullscreen mode, then exit fullscreen mode. The status bar appears at the bottom of the window, despite "Show Status Bar" being unchecked. The only way to get rid of it is to check Show Status Bar, then uncheck it again. The expected behavior would be for the status bar not to appear.

Hi, thanks for the report! Status bar was indeed shown unconditionally.
