How to fix my Video Banner on Mobile View?

[LSAccounting]

As you can see a grey line appeared on my Mobile Version of the Background Video Banner.

What code can I use to fix that?

The desktop version is fine until I minimise my browser.

I checked and found them to be normal. Has your problem been resolved yet?
