Incorrect behaviour of "autoscale" in dark window
When you are in dark window mode, and hit "o", the window is scaled to screen. When you hit "o" again, the window does not scale back to its original size (in contrast to the grey style, here it works). The problem seems to lie in customZoom: implementation in MainWindow.m.
Furthermore, the osd info shown when hitting "o" is the reverse what the user would expect.
