this issue keeps on occurring, haven´t found any way to solve this problem so far so I´ll try here!
Suddenly my keyboard pops up (regularly), mostly it´s just a quick fix but occasionally it turns white and is not functioning at all. Restarting OneNote is not solving the problem, but as soon as I open a different window on top of OneNote (e.g. screenshot) it vanishes, but pops up again as soon as I close the window. So theres 2 things: Keyboard randomly popping up (tried a fix) and it suddenly turning white and not vanishing.
