Unfortunately cannot provide an easy sample project for this. But in a situation with a Virtual TreeView aligned alLeft and another control aligned alClient, both separated with a TSplitter, the horizontal scrollbar did not reliably update when I toggled on or off the columns. When I hovered with the mouse over the scrollbar it updated correctly. The non-client (NC) area was not repainted correctly.

Updating the NC area using code inspired from here #698 solves the problem.
