This issue has been verified Visual studio code 1.98.2(9.0.50 and 9.0.14). Can repro this issue on Android API 33.

This seems likely to be a MAUI specific bug, as .NET for Android does not do anything special with this setting. It just simply puts the AndroidManifest.xml into the APK/AAB.

Moving back to the MAUI repository until further investigation indicates a .NET for Android issue.

Workaround:
When hardware acceleration is disabled (android:hardwareAccelerated="false"), WebView may incorrectly render above other controls. To fix this temporarily, subscribe to your WebView's HandlerChanged event using the following method:

private void WebView_HandlerChanged(object sender, EventArgs e)
{
#if ANDROID
    if (myWebView.Handler?.PlatformView is Android.Webkit.WebView webView &&
        OperatingSystem.IsAndroidVersionAtLeast(23) &&
        webView.Context?.ApplicationInfo?.Flags.HasFlag(Android.Content.PM.ApplicationInfoFlags.HardwareAccelerated) == false)
    {
        webView.SetLayerType(Android.Views.LayerType.Software, null);
    }
#endif
}

This ensures the WebView aligns correctly with the application's software rendering pipeline and maintains proper visual hierarchy.
