Preview in full screen mode has scrollbars I'm on MacOS 10.12.2. I want to use Preview to give a PDF presentation. But here's a screenshot:



It's hard to see, but there's a scrollbar on the right and the bottom has space for a scrollbar but none is there? How can I get rid of these scrollbars, seeing as the entire page fits fine.

The same thing seems to be happening when the PDF first opens, so maybe that's a clue:
In  > System Preferences > General, set "Show scroll bars" to "When scrolling" (or, if you're not using a mouse, "Automatically based on mouse or trackpad"). The scroll bars will be hidden unless you scroll the document.
