Do you have a specific problem that you would like to solve?

Yes, have I not explained my problem well enough?

Exactly. Can you add screenshots?

After spending time trying to document the problem I've narrowed it down to closing one of the bottom three or four tabs.

I had to record it several times due to the wrong data being on the screen but I think I got a clean take this time. Here is a video of the problem in action https://photos.app.goo.gl/Swu6jqyUKFtHXbyE8

Sometimes the problem didn't happen and sometimes it was delayed.

I would describe it as suddenly scrolling to the top of the list. It even continued trying to scroll up after I tried to go down several times in a row until it got all the way to the top of the list.

Hi,

Thank you very much for taking the time to document the problem. The problem can be caused by a virus or simply by the number of tabs you keep, I will give you some solutions:
