Flickering in header

Hi
I've got an annoying thing that happens on page load. A little blue bar (with the hamburger three lines) appears just above my menu, then the menu snaps up and it disappears. It's a split second thing, but annoying and can't be good for CLS. I've tried various things (switching off my cacheing plugin, tweaking settings in the generate press header section, but i can't fathom it.) See if you can see it yourself (I've got a screengrab of it happening too which i can send you).
Thanks

Hi there,
this kind of issue occurs when using Critical CSS optimizations such as the WP Rocket Optimized CSS delivery.
Temporarily disabling WP Rocket is a good way to check for that, make sure to clear browser caches afterwards.
If thats the issue, then its best to speak with WP Rocket about configuring the Optimized CSS Delivery to work with your site.
Ahah, so it is. WP Rocket Optimized CSS unchecked, problem seems to be solved. Thanks again.
Glad to be of help!
