Step by Step:
- Insert manually a new TJvNavigationPane
- Insert manually more than one TJvNavPanelPage
- Inside one of TJvNavPanelPage, create a TListView and put some content on it
- In runtime select the one that you put the TListView
- Try to use the splitter

You should see problems in the render
Even trying to repaint / refresh using the event OnResize, doen't fix it

A workaround to this issue is change the ActivePageIndex on the OnResize event of JvNavigationPane.
It seams that an internal refresh helps someway
NavigationPane.ActivePageIndex := 1;
NavigationPane.ActivePageIndex := 0;

Sorry, the event that I mean was OnSlitterPaint not OnResize as I said
