Display/view splitting

Not sure how to describe this. While working, part of the page will be offset, or split. Used to happen occasionally, but now it's constant. It goes away when I flip pages, or when I use print view, but the next time I do anything (add a text box, add an image, edit something existing, move something, etc.) it happens again. Which makes it VERY hard to align things, or even just type in a text box. See image - right hand page, in one spot a third of the way from top, and another spot third of the way from bottom. 
I've done updates, uninstalled and reinstalled. This is the only program that does it. Other Adobe programs are fine, as are all other programs I use.
