Description

Hello,
I've got a problem with MAUI on Android. I wrote an application to process digital data from an external USB device. I'm creating an ImageSource from a bytes array and binding it to an Image in XAML. New ImageSources are being created very quickly (c.a. 13 per second). Unfortunately, the image is still flickering. At Windows, problems don't occur - the image is displaying almost statically.

My MAUI version:

Problem on Android:
https://github.com/dotnet/maui/assets/24682622/0821abd8-17c3-4663-a4cc-6379a8c5c29e

Correctly working on Windows:

My code:
Page.xaml

<ContentPage.BindingContext>
    <viewModel:UsbTestViewModel />
</ContentPage.BindingContext>

<ScrollView>
    <VerticalStackLayout
        Padding="30,0"
        Spacing="25">
        <Border StrokeThickness="1" Stroke="Blue" HeightRequest="258" WidthRequest="258">
            <Image Source="{Binding ImageSource}" HeightRequest="256" WidthRequest="256" />
        </Border>
    </VerticalStackLayout>
</ScrollView>

UsbTestViewModel.cs

public ImageSource? ImageSource
{
    get => _imageSource;
    set
    {
        _imageSource = value;
        OnPropertyChanged(nameof(ImageSource));
    }
}

//...

// Timer 13 Hz
 private void ImageRenderTimerTick(object? sender, EventArgs e)
 {
     if (RenderTaskManager.RenderedImageSource != null)
     {
         ImageSource = RenderTaskManager.RenderedImageSource;
     }
 }

RenderTaskManager.cs

using SkiaSharp;
//...

 public static ImageSource CreateImageSourceFromByteArray(byte[] bytes)
  {
      var bitmap = new SKBitmap(width, height, SKColorType.Rgba8888, SKAlphaType.Opaque);
 
      ConvertBytesToPixelArray(bytes);
 
      unsafe
      {
          fixed (byte* p = _pixels)
          {
              bitmap.SetPixels((IntPtr)p);
          }
      }
 
      SKData encoded = bitmap.Encode(SKEncodedImageFormat.Png, 100);
      Stream stream = encoded.AsStream();
      return ImageSource.FromStream(() => stream);
  }

Steps to Reproduce

1. Create IDispatcherTimer with TimeSpan 77 milliseconds.

var myTimer = Application.Current?.Dispatcher.CreateTimer();
myTimer.Interval = TimeSpan.FromMilliseconds(77);
timer.Tick += ImageRenderTimerTick;

2. Create ImageRenderTimerTick method where you will be creating ImageSource. You can create image from JPG file - problem still occur.
