Hi Andy Thank you for your respond and the explanation for the observed behavior.
"Do I understand it correctly from this stackoverflow posting that the problem is a momentary adjustment of the columns when the vertical scroll bar appears? And that it works correctly otherwise? Yes, it works correctly otherwise. I would love if you can implement that the vertical scroll bar can to be shown before the layout pass is done. I think it would look a little bit more pro without the movements on first load.
