My recent move from Linux Mint 17.3 to Linux Mint 18.1 brought with it version 18.104.22.168 of LibreOffice. What that brought was an oddity where the default blank document in a fresh LibreOffice Writer session had its only page displayed to the right within the application window. To me, this looks like a bug even if I have a 24″ computer screen.
After some searching, I found a solution that gets a single page displayed in the centre of the application window and not offset to the right as it was. The first step is to go to the Zoom entry within the View menu. Within the sub-menu that is spawned, you need to click on the Zoom… entry to get a dialogue box. That has two columns and the setting that needs changing is under the one named View Layout. For whatever reason, the Columns setting was highlighted with 2 being selected as the number of columns. Choosing the Single Page option instead sorted the problem on clicking the OK button to dismiss the dialogue and the one named Automatic also appears to work. Quite why such an odd default was selected in the first is beyond me though.
