CLS problem with slideout overlay and page hero

Hm..I deactivated the ads and it sadly did not fix the LCP issue (have to trust me there; as you can well imagine I don't want to disable ads on my website for an indeterminate time.

this is difficult it appears.

But maybe you can help to identify the passive listener issue I get instead? there is no scroll to top button or a fancy menu. Is that caused by the parallax hero as well? How can I circumvent that?

You know what - i didn't even notice the Parallax option was enabled ( i should have spotted in the HTML doh ) - try disabling that for the LCP issue... not sure but it may interfere with the LCP measurement.

The Passive Listener issue is actually a core WP Issue:

https://core.trac.wordpress.org/ticket/47510

There are some ways to stop it from being flagged but they generally cause other issues. It can be ignored, it has no bearing on PSI speeds or the LCP.

well i disabled the parallax (totally forgot you could do that, so thx for that). And interestingly enough it did help with the speed (at least according to psi :P) but didn't remove the LCP issue either.

What i cannot explain is this:

That was one of 4 back to back tests i just ran - and it passes LCP, whereas the other three waivered between 3.2 and 3.6s.

Reading some git issues on ChromeDev and Lighthouse and other users have reported similar problems where LCP is not being calculated correctly - seems to me the simulated mobile test they provide has got a few bugs in it....

It may be worth giving it some time to see if Field data collected by Google reflects real world timings and not this simulated 'nonsense'

Last thing you could do is test a post without a featured image background for the hero.
