Is this CSS issue caused by something in Vue?

I have a div with “overflow-x: hidden” to prevent an absolute positioned item (z-index:-1) from overflowing on mobile and causing the page width to be too large and allowing the user to move page to the right.

This works fine in a normal jfiddle.

However, when it’s in WeWeb, it causes the content to refresh whenever the user scrolls up or down. It’s like it is causing the content to be rerendered or something in WeWeb.

Does this have something to do with Vue? Or, what is causing it in WeWeb? Any ideas on how to fix?

The upload of the image failed.

Can you upload a lighter image?
