Hello,

I test your code, I can reproduce this issue in android platform.

For fix this issue, you can add following WebView handler in your layout constructor 's background code to set the layerType to software.

   Microsoft.Maui.Handlers.WebViewHandler.Mapper.AppendToMapping("MyCustomization", (handler, view) =>
        {
#if ANDROID
            handler.PlatformView.SetLayerType(Android.Views.LayerType.Hardware
#endif
        });

And open your AndroidManifest.xml file In your Android manifest file, add the following attribute to the <application> tag to enable hardware acceleration for your entire application:

<application android:hardwareAccelerated="true" ...>
