Blank rectangles on screen while app is open

[Zachariah A DeGraaf]

While any Libre office app is open on my PC, blank, white rectangles appear on my screen. I believe they are related to add-ons as I've had those come up correctly a few times when opening multiple Libre apps and they are the same exact size. These boxes are un-movable, always on top, and block mouse input to the app below it. The only way to get rid of them is to close all Libre apps.
