I can reproduce your issue when changing the background of a user control.

The current workaround I used was changing the background of root UIElement in the control.

    
        
    
    
        Hello World
        Change Background
        
    

public sealed partial class MyUserControl : UserControl
{
    public MyUserControl()
    {
        this.InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        ImageBrush imgB = new ImageBrush();

        BitmapImage btpImg = new BitmapImage();

        btpImg.UriSource = new Uri(@"ms-appx:///images/bg-light-blue.png");

        imgB.ImageSource = btpImg;

        container.Background = imgB;
    }
}
