In the past, in full-screen viewer, when an image had low aspect ratio (i.e. it would fit the screen vertically but will leave black bars on the sides like here) I could press the "down arrow" button and the picture would be maximised on full screen.
Now, if I do that, the picture gets a little bit bigger but leaves empty space all around it (i.e. not only on the sides but also at the top and the bottom). So it never uses as much screen space as it could.
Is it possible to make it work like it used to?
Thanks.
