WPF 应用程序在移动时缓慢/不稳定
我正在创建一个相当基本的 WPF 应用程序外壳。当我使用 DragMove() 函数移动它时，应用程序可以正常移动，但似乎“猛烈”了很多。在我看来，重绘率非常低，使得应用程序看起来缓慢且无响应。
目前，除了调用 DragMove() 之外，没有任何“代码”。
XAML 由带圆角的外边框和设置为 RenderingBias="Performance" 的阴影组成。标题栏和路径上还有一个小渐变。但即使在代码中注释掉这些，仍然会使应用程序在移动时显得不稳定和缓慢。
注意我也在发布版和调试器之外运行了它。
I have a rather basic shell of a WPF app that I am creating. When I move it using the DragMove() function the app moves properly but seems to "jerk" a lot. It seems to me that the redraw rate is very low making the application look slow and unresponsive.
Currently there is no "code" besides a call to DragMove().
The XAML consists of an outer border with rounded corners and drop shadow set to RenderingBias="Performance". There is also a small gradient on the title bar and a path. But even commenting these out of the code still makes the app appear jerky and slow whilst moving.
Note I have ran this in Release and outside the debugger too.

根据经验，尝试删除投影，您会看到更好的性能。

From experience, try removing the drop shadow and you'll see much better perfomance.
