如何防止AIR应用程序在拖动时突然晃动？

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.

Answer 1

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.
