Android透明活动背景重复问题

我已经使用样式进行了透明活动:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">false</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:windowAnimationStyle">@android:style/Animation</item>

    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

布局:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
        android:layout_gravity="bottom"
        android:layout_margin="8dp"
        android:background="@drawable/notification_layout_rect"
        android:id="@+id/clWin"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="250dp">

</LinearLayout>

和代码:

class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    makeStatusBarTransparent()
}

private fun makeStatusBarTransparent() {
    if (Build.VERSION.SDK_INT >= 21) {
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        window.statusBarColor = resources.getColor(android.R.color.transparent)
    }
}

}

问题:但是,当我多次单击“概述”导航按钮时,我得到了背景复制效果。有解决此问题的方法吗?

问题至少可以在android 5.1.1和7.0上再现
