As title.

when putting the bag frame at some place, it will slightly move the position after toggle display bags on then off.

to reproduce this movement need to try by positioning the bag frame in certain area.

Yep, this is a known issue, and happens if you position your frame in specific spots. It basically is just due to how I automatically save position data.

As far as I can think of, there is nothing more to be done here: position is only saved when the user moves the bags. As the anchor is automatically determined, it might go in a direction the user does not want to.
Solutions are:

1. Make the process manual
2. Always anchor to bottom

I don't like any.

I did a modification a while ago that does not fix it, but reduces the chances of happening.
