Map cuts in the bottom in some zoom / when scrolling up

Hi,    I am using Chrome (specs in the end) and when scrolling the map in some zoom number it cuts the map´s end.   For example it happens with 90% zoom I have no idea why.

This a long -standing display bug with Roll20. Don't worry, your maps are not losing any data. Someone recently posted a potential cause (<a href="https://app.roll20.net/forum/post/8455731/canvas-scrolling-bug-with-likely-cause-in-code" rel="nofollow">https://app.roll20.net/forum/post/8455731/canvas-scrolling-bug-with-likely-cause-in-code</a>) and the devs are looking at it. Hopefully they are right and there is a fix soon.
