Android 12 splash white background

I was trying to add support to the Android 12 splash screen. Here's my v31/styles.xml

<resources>

<style name="SplashTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:navigationBarColor">@android:color/transparent</item>
    <item name="android:windowSplashScreenAnimatedIcon">@drawable/ic_launcher_foreground</item>
    <item name="android:windowSplashScreenIconBackgroundColor">#FF3044</item>
    <item name="android:windowSplashScreenBackground">#FF3044</item>
</style>

</resources>

I am able to see a white screen after the new splash. That white screen is the android:windowBackground but if I tried to set it as @null, I am getting inverted splash at the place of the white screen. How to remove that white background after the splash? Splash API was designed to replace windowBackground I guess.

App flow -> SplashActivity (with the mentioned theme) and then I pause the preDraw method using a ViewModel then navigate to another activity.

SplashActivity.kt - onCreate()

val content: View = findViewById(android.R.id.content)
    content.viewTreeObserver.addOnPreDrawListener(
        object : ViewTreeObserver.OnPreDrawListener {
            override fun onPreDraw(): Boolean {
                return if (viewModel.appInit()) {
                    navigateToHome()
                    content.viewTreeObserver.removeOnPreDrawListener(this)
                    true
                } else {
                    false
                }
            }
        }
    )

HomeActivity doesn't have any theme. When I add <item name="android:windowBackground">@color/android:black</item> in the Splash's theme, instead of the white screen, I'm getting the black one.
