WPF选项卡控制选项卡项目高CPU使用率

在我的WPF应用程序中，我有一个

TabControl

和三个

TabItems

。每个

TabItem

都有一个

ItemsControl

，其中

ItemsSource

绑定到Viewmodel中的

observeCollection

。如果我打开第一个和第二个

选项卡项

，CPU使用率为70%，我不知道为什么

我的第一个想法是，数据绑定导致了这种情况。因此，我从这个

选项卡项中删除了所有绑定。但是，即使第三个
选项卡item
没有被调用的内容或代码，CPU使用率仍然很高。如果我切换回第一个和第二个
选项卡项
，CPU使用率将恢复正常

所以我希望你能帮助我
 第三个选项卡中是否有情节提要或类似动画？没有。我将添加一个示例您是否注意到输出（调试）窗口中有任何异常？我还建议您在CPU使用率上升时单击“暂停”按钮，然后查看线程窗口（Debug/Windows/threads）中可能导致问题的线程。确定输出窗口仅显示：跳过加载符号。模块已优化，并且调试器选项“仅我的代码”已启用。如何查看线程是否导致问题？我知道这个窗口，但我不熟悉它。如果我暂停了主线程，CPU使用率为0。因此，我想其他线程不应对如此高的CPU使用率负责。还是我错了？
