Any fix for this, xD I'm going to have to migrate the project to Xamarin.

I spent a few hours to analyze this problem.

This bug was created following this pull request: https://github.com/dotnet/maui/pull/7348

While waiting for Microsoft to permanently fix this bug, the workaround consists of redoing the clear before each source image change.

Below is an example of code to add the clear in the source image mapping.

using Microsoft.Maui.Handlers;
using Microsoft.Maui.Platform;

namespace MauiCanvas;

public static class MauiProgram
{
	public static MauiApp CreateMauiApp()
	{
		var builder = MauiApp.CreateBuilder();
		builder
			.UseMauiApp<App>()
			.ConfigureFonts(fonts =>
			{
				fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
				fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
			});

#if __ANDROID__
        ImageHandler.Mapper.PrependToMapping(nameof(Microsoft.Maui.IImage.Source), (handler, view) => PrependToMappingImageSource(handler, view));
#endif

        return builder.Build();
	}

#if __ANDROID__
    public static void PrependToMappingImageSource(IImageHandler handler, Microsoft.Maui.IImage image)
    {
        handler.PlatformView?.Clear();
    }
#endif

}
