Just a few things, this happens randomly.... usually after putting a lot of elements on the whiteboard, then erasing and doing it again....
There are doubles in the text... after text is typed, it seems to get a shadow effect. Another issue is after erasing one or two elements remain
and can not be deleted. however it is erased on the viewers screens
