Hi @Mohammed Ismail, I've checked this issue on a Microsoft Surface Pen & Touch but cannot reproduce it. In my end there is no differences between closing tabs in tablet mode and desktop mode. It would be helpfully that you can and a short video helping to reproduce the issue. Thanks for your contribution.

The issue is especially noticeable when I started to close tabs from the middle, the animation is less smooth compared to the animation in normal mode
