Hi, I think there’s a bug in FlashPlayer 10 Graphics:  
When you set LineScaleMode.NONE + JointStyle.MITER, draw a line then change the thickness of that line then the player won’t clear the border line correctly:

```auto

var S:Sprite = new Sprite();
var G:Graphics = S.graphics;
var thickness:Number = 1;
var i:int = 1;

S.x = S.y = 200;
addChild(S);

function draw():void
{
    G.clear();
    G.lineStyle(thickness, 0xFF0000, 1, true, LineScaleMode.NONE, CapsStyle.SQUARE, JointStyle.MITER);
    G.drawRect(-50, -50, 100, 100);
}

setInterval(function()
{
    thickness += i;
    draw();
    S.rotation += i * 2;
    if ((thickness>50) || (thickness==1)) i = -i;
}, 20);
}, 20);

```

It works correctly in FlashPlayer 9.
