Mobile Header Flashes White During Scroll

Hi,

I’m experiencing an issue with the Enfold theme on mobile/small screens:
When the hamburger menu is active, the top header area briefly flashes white when I start scrolling down. After this quick flash, it fades back to the intended header background color.

The issue occurs consistently on my own website, but to make sure it wasn’t caused by a local customization, I tested it on several official Enfold demos as well. The same white flash appears in the Enfold Knowledgebase Demo, so the bug seems to affect Enfold’s default configuration too.

It happens only on narrow/mobile viewports and only at the moment when the page first starts scrolling. The header appears to transition through a white state before applying its final background color.

Could you please take a look or let me know if there’s a known fix?

Thanks!
