我尝试在WPF中创建一个动画复选框，类似于this one。
此问题与this one不重复，因为动画的帧速率没有问题。
动画和故事板已经到位，并且工作正常，但是对于某些rason来说，当动画正在播放时，看起来整个事情正在发生震动，如here所示。效果最好在盒子的右边缘看到。
以下是自定义复选框的XAML源代码。我不认为有必要发布代码，因为除了RoutedEvent定义（Timeline.DesiredFrameRate和SnapsToDevicePixels）之外，它不包含任何其他内容。
true
我已经尝试通过将 <!-- https://mvnrepository.com/artifact/com.databricks/spark-xml -->
<dependency>
<groupId>com.databricks</groupId>
<artifactId>spark-xml_2.11</artifactId>
<version>0.4.1</version>
</dependency>
设置为60来增加故事板帧率，正如您在代码中看到的那样，但它对动画的不稳定性没有影响。
我还尝试将 <!-- Create Form -->

<form action="retrieve.php" method="post">

，希望它能改善动画效果。
这种震动效果的原因可能是什么，我该如何消除它？
