winforms visual-studio-2008 resize flicker skin

I'm trying to create some skinned forms (just the border and caption) with a different approach than you usually see but I'm having some issues with form flickering while I resize the form.

I don't know how else to explain the problem, so here's a video I created to demonstrate the problem: http://www.screencast.com/t/AIqK9Szmz

Also, here's a VS2008 test solution with the whole code that repaints the form borders:http://stuff.nazgulled.net/misc/TestForm.zip

Hope someone can help me get rid of the flicker...

That's what I use in my base form's constructor:

this.SetStyle( ControlStyles.AllPaintingInWmPaint, true );
this.SetStyle( ControlStyles.UserPaint, true );
this.SetStyle( ControlStyles.OptimizedDoubleBuffer, true );
this.SetStyle( ControlStyles.ResizeRedraw, true );

I think the key is the use of "AllPaintingInWmPaint".
