Screenshot of layout issue

The header intermittently renders halfway down the page instead of at the top of the page after scrolling down the page. It seems more prevalent on iPads than laptops though it does happen on both platforms. It does not occur on iPhones because the header on the homepage scrolls off the screen instead of remaining fixed.

Could it be the combination of backdrop-filter and position: fixed?</pre>
