Activity list jumps to top after some short time

Created by: dfn-certling

If I list for example all activities for a month, the list is obviously larger than one screen. When I scroll down this list some way, the list jumps back to the top on its own after some time of waiting. Sometimes its 5 seconds, sometimes a minute.

I would expect the list to stay at the scrolled to position.

This is with hamster 3.0.1 on SUSE Tumbleweed using lightdm.

Anything else I can provide to help debug this?
