Passive listeners to improve scrolling performance
10 replies · Started by Uwe on January 30, 2020
Hello Support-Team,
I made a lighthouse analyze.
One of the errors was this:
"Does not use passive listeners to improve scrolling performance."
Consider marking your touch and wheel event listeners as passive to improve your page's scroll performance.
I am not a specialist and do not know is this error about of the theme or in WordPress?
Do you know how to resolve the problem?
Hi there,
its a WordPress 'bug' - there is a ticket open relating to a fix for this:
https://core.trac.wordpress.org/ticket/47510
It's not an issue i would be overly concerned about.
Danke David!
You're welcome
Looks like that bug isn't getting fixed anytime soon. I have placed some javascript in my footer that works.
I not sure if posting that code here is a good idea so this is the link to the page.
Wordpress and best practice with passive event listeners
Cheers!
Thanks for sharing Grant :)
Bad news! The new version (beta - rc3) of WordPress does not seem to fix this issue. My code posted still works great.
Hello, Grant.
How do you insert that code? Can you show me, I'm not developer. Thanks
I tried the javascript code above and it broke the primary navigation when I used submenus.
I tried this code here on this page and it seems to work fine

Another words the first solution doesn't seem to be compatible with GeneratePress while the second one is.
Thanks for sharing!
The code I posted doesn't assume that you use jQuery. People should use what works for them.
Cheers!
