在 SMFPlayer 问题上方显示图像

Question

图像（Image 类）放置在 SMFPlayer 上方（两个元素均在代码隐藏中创建）。图片的Z-index为SMFPlayer的Z-Index + 1。图片根据SMFPlayer的播放进度调整大小（调整宽度）。

    videoPlayer = new SMFPlayer();
    videoPlayer.Width = 1920;
    videoPlayer.Height = 1080;
    videoPlayer.Margin = new Thickness(1920, 0, 0, 0);
    PlaylistItem item = new PlaylistItem();
    Random r = new Random();
    item.MediaSource = new Uri("video.wmv");
    item.DeliveryMethod = DeliveryMethods.ProgressiveDownload;
    videoPlayer.Playlist.Add(item);
    videoPlayer.AutoPlay = true;
    videoPlayer.AutoLoad = true;
    videoPlayer.IsControlStripVisible = false;
    videoPlayer.PlaylistVisibility = FeatureVisibility.Disabled;
    videoPlayer.MediaEnded += new EventHandler(player_MediaEnded);
    LayoutRoot.Children.Add(videoPlayer);

            bar_yellow3 = new Image();
            bar_yellow3.Source = new BitmapImage(new Uri("/SMF_ProgressiveDownload1;component/assets/bar_y.png", UriKind.Relative));
            bar_yellow3.Width = 775;
            bar_yellow3.Height = 34;
            bar_yellow3.Margin = new Thickness(2948,1034,0,0);
            bar_yellow3.Stretch = Stretch.Fill;
            bar_yellow3.VerticalAlignment = VerticalAlignment.Top;
            bar_yellow3.HorizontalAlignment = HorizontalAlignment.Left;
            LayoutRoot.Children.Add(bar_yellow3);

但是，当播放进度低于 20% 时，图像会随机闪烁。当SMFPlayer设置为不可见（Visibility.Collapsed）时，图片正常。

我尝试调用Image的更新函数，即：bar_yellow3.UpdateLayout();，但该方法并没有解决闪烁的问题。

有什么办法吗？

尝试使用效果（Shazzam 会帮助你）而不是使用 Z 顺序。
