[WPF] records the problem caused by a Win8 "zoom level" setting. wpfwin8

This is my computer's resolution settings:

The key is to set the zoom level to "Greater", that is, 150%.

The screen resolution obtained by using various methods in WinForm is scaled, but the mouse position in the mouse event is also consistent with that in the coordinate system:

The resolution obtained here is scaled, but the mouse coordinates at this time are completely different from those of the coordinate system:

We can see that the coordinate system of the mouse position is consistent with the actual resolution, that is, 1920*1080, but all other coordinates are in the 1280*720 coordinate system.
