background image being cropped in tabs layout?

Hi there, if you look at my homepage here: http://www.jamjosandbox.com/hydrolight/ and you look specifically at the Tabs area. You can see the first tab, the image is a little bit narrow on height and very much cropped in this view. It should look like the attached here.

basically I am not sure why the image is being cropped and I would like it not to be cropped here.

Thanks in advance.

Hello,

Your image size is 1200 x 773, so on bigger screen resolution it must be stretched, try to use bigger image, or you can also try to disable "Use JS Parallax engine" option from Appearance -> Customizer -> Features section.
