All of a sudden, a couple weeks ago, I've noticed that whenever I hover my mouse at the top of my chrome browser while in fullscreen, when the top menu bar appears it shifts the whole webpage a couple inches down. It's a really clumsy interface experience - when reading ebooks on google play books, to accidentally hover my mouse to the top of the webpage causes the page to shift and subsequently reformat me to a new page in the book.
The menu bar used to just come down over the webpage, covering whatever inch or two it took up. Now the whole thing reformats. Any solutions to this?
I understand this is is similar to other threads, but what I'm looking for is not for the menu bar to be there permanently, just that when I hover my mouse, it doesn't reformat the page as it is now doing.
