The reason over here is, body element has a different background compared to html element, and body element background is rendered in the viewport area, and when you scroll the page you see the background color set on html element.
Solution can be to set same background color on both these elements

To Fix the issue, you need to check the class of that particular section from Developer tool, once you get the class then keep the class into any of your additional style class, then set background color as required.
