Animation type of Infinite can not dispose, Memory leak

[peng007ge]

Describe the bug
First,
Infinite Animation in xaml failed to release.

<Style Selector="DockPanel[IsVisible=true]">
    <Style.Animations>
	    <Animation Duration="0:0:0.8" IterationCount="Infinite" PlaybackDirection="Alternate">
		    <KeyFrame Cue="0%">
			    <Setter Property="Opacity" Value="0.2"/>
		    </KeyFrame>
		    <KeyFrame Cue="100%">
			    <Setter Property="Opacity" Value="1.0"/>
		    </KeyFrame>
	    </Animation>
    </Style.Animations>
</Style>

To Reproduce
then,I try.

       Animation animation = null;
       IDisposable subscriptions = null;
       private void MenuItem_Click(object sender, RoutedEventArgs e)
        {
            if (animation == null)
            {
                animation = new Animation
                {
                    Duration = TimeSpan.FromSeconds(0.8),
                    IterationCount = IterationCount.Infinite,
                    PlaybackDirection = PlaybackDirection.Alternate,
                    Children =
                    {
                        new KeyFrame
                        {
                            Cue= new Cue(0),
                            Setters=
                            {
                                new Setter(OpacityProperty,0.2)
                            }
                        },
                        new KeyFrame
                        {
                            Cue= new Cue(1.0),
                            Setters=
                            {
                                new Setter(OpacityProperty,1.0)
                            }
                        }
                    }
                };
                var rec = this.FindControl<DockPanel>("rec");
                subscriptions = animation.Apply(rec, rec.Clock, Observable.Return(true), () => { });
            }
            else
            {
                subscriptions?.Dispose();//not work
                //this is work
                animation.IterationCount = new IterationCount(0);
                animation = null;
            }
}

I hope can release Animation in xaml when my control removed.

I got same problem. I have a modal window (ShowDialog) with infinite animation. After closing whis window, animation keep working, consumming memory, CPU and GPU. Opening this window multiple times consumes more and more memory and CPU/GPU. So after some time application become unusable and must be restarted.

Probably,It it fixed on ver 11.x,I am not found the bug now

@peng007ge closing this as it's solved for the OP.

Note

Animations still have high memory usage, we are aware of. But it shouldn't be leaking anymore

@ds1709 let us know your version you use. If it's 11.1 beta, open a new issue with a minimum sample attached. Thx 🙏
