Request for Help: Staging Site Layout Issue with Mobile Nav

Hey team, I could use your help. We’re experiencing a layout issue on the staging site a build set to launch later this week pending final creative to replace the AI placeholder crap: https://nova-dental-v2.design.webflow.com/?locale=en&workflow=sitePreview and I could really use someones help. There’s a subtle but persistent glitch occurring with the hero section — particularly when opening and closing the mobile nav. It’s causing a visual jump or shift in the background, and I haven’t been able to pin down the cause. I’ve tried the usual suspects (overflow handling, height constraints, 100svh adjustments, etc.) but no dice. Would appreciate it if someone could take a look and let me know what I’ve missed. Happy to give access or jump on a Loom if that’s helpful. Thanks in advance!!
