Clicking the title bar with the mouse causes frame drops and freezes

[chinware]

Describe the bug

When the mouse clicks on the window title bar, the page will be stuck for about 100 milliseconds, and the page animation will drop frames at this time. If you right-click, the animation will be stuck from the time the button is pressed to the time it is released.

To Reproduce

Click the title bar and look carefully at the mouse pointer. It will flash. At this time, if the page has animation, the frame rate will also be dropped.

Expected behavior

When you press the mouse, there should be no frame drops.

It is expected for apps that don't use WinUIComposition/DirectComposition rendering. Have you changed any Win32 platform options from defaults?

I should have used the default configuration. I asked several friends in the community and they all had this problem. It doesn't matter if it's a custom titlebar or the system's built-in one. As long as you click in the titlebar area, there will be problems.
