I've set the display in Draft View to 125 percent, which I understand to control Full Screen View. Yet Full Screen View persists at 100 percent. What have I overlooked?
Full Screen has its own zoom settings. Once you've entered full screen adjust the zoom to your liking. You can do so using either the View menu (let the mouse linger in the menu bar area and the bar will appear) or simply activate your zoom in/out keyboard shortcuts.
Were you by any chance letting the mouse linger in the full screen gutter? Apparently the mouse has to be within the text area for the menu bar to appear. I'll file a bug on this.
