尝试将 CustomAppSkin 更新为：

<?xml version="1.0" encoding="utf-8"?>
<s:Skin name="CustomApplicationSkin"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        alpha.disabled="0.5">
    <s:states>
        <s:State name="normal" />
        <s:State name="disabled" />
    </s:states>

    <fx:Metadata>
        <![CDATA[ 
        [HostComponent("spark.components.Application")]
        ]]>
    </fx:Metadata> 

    <!-- fill -->
    <s:HGroup width="100%" height="100%" verticalAlign="middle" horizontalAlign="center">
        <s:BitmapImage id="img" fillMode="clip" horizontalCenter="0" verticalCenter="0" 
                       source="@Embed('assets/images/bg_with_Steps.png')"
                       smooth="true" 
                       left="0" right="0"
                       top="0" bottom="0" />
    </s:HGroup>
</s:Skin>
