Bug title:ScrollView can cause controls to become blurred when scrolling

Describe the bug

ScrollView can cause controls to become blurred when scrolling

----------------------------

ScrollView 在滚动的时候会导致控件变模糊

---

As shown in the figure, ItemsView uses ScrollView as the implementation for scrolling content. However, during the usage process, it was found that there is a chance that the content becomes blurry when scrolling. When the content scrolls to the boundary area, it returns to normal. It is hoped that this bug can be fixed in the next version.

----------------------------

如图所示，ItemsView 使用 ScrollView 用作滚动内容的实现，但在使用的过程中发现，滚动时有几率导致内容变模糊，内容滚动到边界区域时，内容又变正常了，希望能在下一个版本中修复该 bug。

This might be related to #10416.
Try wrapping the ItemsView in a Border and see if that changes anything?

<ScrollView>
    <Border>
        <ItemsView>
            <!-- ... -->
        </ItemsView>
    </Border>
</ScrollView>

Can this approach enable ui virtualization of the ItemsView?

Yeah, this is why I prefer to use ItemsRepeater

@Gaoyifei1011
I noticed that both issues (this one and #10416) are reproducible only when the SettingsCard is used. Can you reproduce this with other controls? Maybe it's an issue with the WCT SettingsCard control.

What controls does the SettingsCard control consist of? Grid?
I'm sorry, but I haven't used SettingsCard in my application, so I'm not very familiar with this control

-----------------------------

SettingsCard 这个控件是什么控件组成的？ Grid 吗？
很抱歉，我并没有在我的应用中使用到 SettingsCard，所以我不是很了解这个控件

Ok. This issue has been around for a long time and I haven't seen Microsoft solve it yet, so I temporarily switched back to ListView in my application. Moreover, according to the Issue, it can be seen that there seems to be a memory leak in ItemsView?

-----------------------------

好吧。这个问题已经出现了很长时间，一直也没有看到微软解决，所以我暂时在我的应用中切回到 ListView 了。而且根据 Issue 可以看到 ItemsView 好像有内存泄漏？
