Big dots when grouping or exporting/printing
I already noticed the problem in 16.1 and it is still there in 16.2.
When I write on the board by hand and then group different elements, e.g. to shrink them or move them, I see big dots where they should not be. This also happens when I want to print pages or export them as pdf. Unfortunately it happens almost all the time and I have not idea how to prevent it happening.
