How to prevent AIR application from jerking around while dragging? - actionscript-3

Question

I've created an AIR application and it seems to be working fine but when I drag the title bar to move the native window it shakes violently and have seizures while it's dragging about.
FYI It does eventually end up where I want it to be when I stop moving the mouse.
I'm using Flex 4.6 and AIR 3.6 on Mac OSX 10.10.5. It's a s:WindowedApplication I'm also using the DragManager on a list in part of the application if that matters but it is not enabled until the user clicks into the list and moves more than a certain number of pixels.
Here is my descriptor file minus name and version info:
<application xmlns="http://ns.adobe.com/air/application/3.6">
<initialWindow>
<autoOrients>false</autoOrients>
<fullScreen>false</fullScreen>
<visible>false</visible>
</initialWindow>
</application>
On initialize I run this:
protected function initializeHandler(event:FlexEvent):void {
width = Capabilities.screenResolutionX * .96;
height = Capabilities.screenResolutionY * .9;
nativeWindow.x = (Screen.mainScreen.bounds.width - width)/2;
nativeWindow.y = (Screen.mainScreen.bounds.height - height)/2;
}
UPDATE:
I removed the main view component so it is an empty application and it drags around smoothly.
UPDATE 2:
I added the main view back in and dragged around step by step along the way. It appears to start happening when I've loaded a second Application (called a sub application) into the main application. I'm not sure though.

This happens in numerous number of my applications. It is probably because I have a component inside my application file set to size to 100% of the application. But I have not verified this on all my apps.
The solution is to resize the AIR app. After I resize it it works fine. I can drag it around and it works as expected. I think this is an AIR bug.
