就是 MPO（Windows Multiplane Overlay）问题， Win11 打上这个注册表重启以后，问题就解决了；
Win10 看到后面有人试了一下？搞不懂，主要这个机制是 Win11 才引入的，所以应该没用吧。

1. Windows Registry Editor Version 5.00
   
2. 
   
3. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm]
   
4. "OverlayMinFPS"=dword:00000000

Path	Value	Data
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Dwm	OverlayMinFPS	A DWORD. If this value is present and set to zero, the Desktop Window Manager disables its minimum frame rate requirement for assigning DirectX swap chains to overlay planes in hardware that supports overlays. This makes it more likely that a low frame rate swap chain will get assigned and stay assigned to an overlay plane, if available. This mechanism was introduced in its present form in Windows 11. This registry value may be modified or removed in future releases.
