Please try added example. It is nearly the same as in the bugtracker but with aligned scrollbox and a scrollbar to switch the height of Panel3. Is it so as you want?
No. Attached (I hope ) a better example. The user can resize Panel2 with the Form and can resize Panel3 with the TrackBar. But want higher Panel3 than the available space. For solve this the whole thing sit in a ScrollBox. And the "InvalidatePreferredSize loop detected" problem breaks this solution. I completely don't understand why Panel3 not resizable to lower than border of the ScrollBox. Panel3 not have a bottom anchor. From my POV (and brain) the anchors are correct. Panel2 anchored to bottom of Panel1, Panel3 anchored to bottom of Panel2 and bottom of Panel3 not anchored.
Why got different error message with the TrackBar and OnClick resize of Panel3?
