SDK 3.3.0 - Android - Window not fullscreen

When I compile my (existing) app with 3.3.0 GA the following window (webview, view_bg) is not filling out the whole window space. Its only a small view in the top left corner and I still see my splashscreen.

"Window": {
    exitOnClose: true,
    left: 0,
    right: 0,
    bottom: 0,
    top: 0,navBarHidden:true, backgroundColor:"#fff",fullscreen:true
}
 
"#webview":{
    enableZoomControls: false,
    left: 0,
    right: 0,
    bottom: 0,
    top: 0,
    width:Ti.UI.FILL,
    height:Ti.UI.FILL,
    userAgent: "MobileApp",
    scalesPageToFit: true
}
 
"#view_bg":{
    left: 0,
    right: 0,
    bottom: 0,
    top: 0,
    visible: false,
    touchEnabled: false
}
 
"#view_black":{
    backgroundColor: "#000",
    opacity: 0.5,
    left: 0,
    right: 0,
    bottom: 0,
    top: 0
}

<Alloy>
    <Window>
 
        <WebView id="webview" url="http://www.google.de"></WebView>
        <View id="view_bg">
            <View id="view_black" />
            <ActivityIndicator id="activity"></ActivityIndicator>
        </View>
        <Button id="btn_back" titleid="back"></Button>
    </Window>
</Alloy>

with 3.2.3 it was working fine. Do I need to change something with the windows for 3.3.0?
