Lighttable UI is not updated (redrawn) in the full-screen when screen resolution is bellow or equal to the HiDPI mode of 1280x800px
Specifically at the native resolution 1280x800px@2x of the Macbook-pro retina the UI of the Lighttable, while in the full-screen mode, is not redrawn. This does not happen in the window mode or at higher resolutions. The program still reacts to the keyboard shortcuts and partially to the mouse input, but the UI does not react (is not redrawn).
Interestingly at the HiDPI resolution of 1024x640@2x, not only the Lighttable but the Darkroom UI as well is not redrawn ones in the full screen mode and only in full-screen mode.
