SYMPTOMS
If an application contains a layered window that is translucent, and the layered window has a movable child window, the screen is not correctly painted if the contents of the child window change. This problem may occur when you use the SetLayeredWindowAttributes Windows Graphics Device Interface (GDI) function or when you use the Microsoft Windows Forms TransparencyKey property to set the opacity and to set the transparency color key of the layered window. For example, if a layered window contains a list view, the layered window may appear as if the list view headers or the list does not scroll correctly and that the screen does not repaint correctly.



CAUSE
The child window area was not invalidated correctly by the GDI.
