`grabWindow()` does not work in MacOS 12.6（Not the desired effect）
The expectation is to capture the entire desktop (including windows, displayed on top of the desktop wallpaper); however, only the desktop (and no other windows) is actually captured.

For example, run this example from screenshot to reproduce.

If it does not appear, click the "New ScreenShot" button and try a few more times. Or clean up the project and edit it again. It is easy to reproduce；release is easier to reproduce than debug mode
