Hello,
You have the “Cover” option enabled for the bg image. https://take.ms/GO6IR
Here is an explanation of the cover value:
cover
Scales the image (while preserving its ratio) to the smallest possible size to fill the container (that is: both its height and width completely cover the container), leaving no empty space. If the proportions of the background differ from the element, the image is cropped either vertically or horizontally.https://developer.mozilla.org/en-US/docs/Web/CSS/background-size
Thus, if the picture is zoomed-in, it is normal and the right work for the cover option because such works CSS.
I suggest you upload an image with a bigger resolution. https://take.ms/Uueaa
Kind Regards
