New Apple.com navigation bar – unusable?

I'm on a fairly recent Macbook Air 2020 (Intel i7). Hovering over the top menu, a full-page animation badly stutters to reveal a few text links. It seems I'm barely getting a few frames per second. Worse yet, the overlay gets stuck in an open position, blocking the content, until I refresh the page, and scroll down avoiding the menu. That's in Chrome. Safari is slightly smoother, but the animation still obviously stutters.

A trick to buy new hardware? \s
