Given Alex's point, that SWF size can change dynamically, getting your measure/updateDisplayList functionality right might be difficult.
An easy solution, in my mind, would be:
1) Set the width/height of your custom class to 100%, so it fills
your title window (or do whatever you want to give it a size...but if
you don't give it a size, and don't implement measure(), it will default
to 0x0).
2) In your createChildren() function of your custom component,
create a shape, addChild it, draw a rectangle into it, and add it as a
mask:
override protected function createChildren():void
{
var tmp:Shape = new Shape();
tmp.beginFill(0);
tmp.drawRect(0,0,10,10);
tmp.endFill();
addChild(tmp);
mask = tmp;
}
3) In your updateDisplayList(), set the width/height of your mask
to match your unscaled width/height:
override protected function updateDisplayList(...):void
{
mask.width = unscaledWidth;
mask.height = unscaledHeight;
}
Now you don't need to rely on the masking capabilities of
TitleWindow...your custom component self-masks.

Are you reporting a measured or explicit widht/height in measure() and
matching that in updateDisplayList()?
If you base it on the SWF size, keep in mind that the SWF's size may
change and measure incorrectly.

I'm having a very similar issue. Did you ever come up with a good
resolution or at least an understanding as to what was going on?
