The documentation for OptimizedDoubleBuffer indicates that it will help to reduce flicker and has the same effect as setting the UserPaint and AllPaintingInWmPaint ControlStyles to true. However, if the OptimizedDoubleBuffer ControlStyle is set to true without setting UserPaint and AllPaintingInWmPaint there is no visible reduction of flickering. Setting the UserPaint and AllPaintingInWmPaint ControlStyles will result in the same reduced flicker optimisation as in Visual Studio 2003 when setting the DoubleBuffer, UserPaint and AllPaintingInWmPaint ControlStyles.
