Secondary display getting blacked out

Hi. I used to be able to maximize (fullscreen) a Firefox window in either my main display or my connected external display and the unused display would remain available. As of the last update the unused display is being blacked out. How can I revert this so I can use the other display? I have already tried turning hardware acceleration off and back on and it still does not work.
