Wallpaper sizing Sonoma Macbook Air M3

How to fix this (settings only)

1. Open System Preferences
2. Search "Change the wallpaper"
3. Beside the wallpaper name, there is something like an aspect ratio option.
4. (example) The following options are Fill Screen, Fit to Screen, Stretch to Fill Screen, and Center.

If this doesn't work, do the following:

1. Look for a wallpaper on the internet.
2. Follow the previous steps.
3. If it still doesn't work, just ignore the wallpaper.

Not sure what that means. The wrong ratio means the image is distorted. In the case of the Scotland Castle, it takes a fairly long time before it reaches and overflies the castle. Nothing to do with it being the wrong ratio.

Once Scotland Castle is downloaded, or any other Screen Saver, it does not need the ratio changed, nor can it be.
