Wix Pro Gallery Flickering Issues

We are having issues with our Wix Pro Galleries. When the page loads, both on the preview and live site versions, the media within the galleries flickers once or twice while the page is scrolled.

We are using Wix Studio, and we have set up a dynamic page with multiple sections that contain one gallery and/or text. The content is loaded from the CMS, and when a boolean value in the collection is checked, each section is expanded or collapsed on the site accordingly. (This last part is handled with code.)

It’s not clear what’s causing the issue; we’ve tried changing different settings within the galleries themselves, but this has not solved the flickering. Removing the code to expand/collapse a section or replacing it with a show/hide function does not seem to solve the problem either.

Has anyone encountered such an issue before? We have contacted Wix Support, and they have yet to investigate this matter.

Here’s a recording of what happens on the site. This can be seen in all of the dynamic pages with galleries: Wix Pro Gallery Flickering on Load | Loom
