Possible BUG: setting height/width makes a mess up

• Windows 7 x64
• Ti SDK 3.5.0 and 3.4.1
• Studio: 3.4.1.20.....
• Alloy
• Target: Genymotion 2.3.1 and TiShadow on Galaxy S3
• default unit: px or dp

Hi, I think it's a bug: if i create a very simple window and set height and width the layout messed up. Example:

index.xml

<Alloy>
    <Window id="winIndex">
        <ImageView image="letters/a.jpg"></ImageView>   
    </Window>
</Alloy>

index.tss

"#winIndex":{
    layout: "vertical",
    backgroundColor: "#abc",    
}

the followin index.js code file works fine:

index.js

$.winIndex.open();

But this creates a mess up:

$.winIndex.width = 720; // the real width of the device
// also if I use Titanium.Platform.displayCaps.platformWidth
$.winIndex.open(); // The imageView is shifted on the right
