------- Additional Comments From burnus@gmx.de 2005-26-04 15:05 ------- I see the same (cf. bug 2320). In my MDI application it overdraws everything within the main window: child windows including the caption bar, toolbars and status bars. Actually, here it only overdraws everything with the (OpenGL) background colour and the actual drawing seems to be correctly clipped (though it might to be a bit too low).
