Continuous scrolling not working

[SikandAlex]

I'm using Gatsby.js to render a landing page. Even with autofill prop set to true, the components in my marquee disappear and then "jump" in.

The elements in the marquee disappear after 1-2 full cycles (where everything is fine)

After the "DearMedia" image reaches exactly 50% of the way through the scroll container, the images suddenly instantly appear again.

I'm using the StaticImage component from Gatsby to render my images, which are the used as component children in the Marquee component.
