Wierd Navbar Open Glitch with Background Video

Hey Guys!

I have a really strange issue.

Please open this site on mobile (Issue cannot be seen in Inspect) → https://5p-agency.webflow.io/

When you open the menu… 1/4 menu has a lower z index than the menu itself even when its 100% width, but after you scroll everything seems fine…

I couldn’t find the issue even in mobile inspect in Safari.

Fun Fact - When you make a Screenshot or Start recording your screen everything is fine.
Also, the issue disappears when you delete the background video element.

Any help? Thanks
