Desktop icons and a busy wallpaper show up in full-screen shots and in any rectangle that includes the desktop. This control hides that clutter. It does not delay the shot, and it does not capture a single window by itself.
Hide the clutter
- Before the capture, turn on hide desktop icons in Shoverlay.
- If the wallpaper itself is the problem, replace the desktop with a wallpaper you choose or with a solid color.
- Take the fullscreen shot, or an area that includes the desktop.
A clean window background applies when you are shooting a window and want that window’s surroundings simplified. Turn it on for a window shot, not as a substitute for hiding icons on the desktop.
If icons are still in the picture
The hide-icons option has to be on before the capture, not after. A window-only shot never included the desktop icons. Check which mode you ran.
Install Shoverlay on the Mac App Store.
