[Zubersoft]

I believe I have located the cause for this. It has to do with the scaling calculations, and some rounding issues were causing annotations to appear to move after they are created. I've adjusted the code to eliminate these rounding issues, and the annotations now don't move at all. On my Samsung Tab S4, this movement was only a couple of pixels, which is only noticeable when zoomed in a fair amount. Hopefully this will address what you are seeing. If you can confirm that this issue is addressed after version 3.1.0 is released, I would appreciate it. 

Thanks,
Mike
