Hi get a 99 score in lighthouse and also in PageSpeed Insights BUT PageSpeed Insights gives me ( for desktop ) a FAIL because it thinks I have a 0,67 CLS issue

I did test it with GTmetrix, webvitals Debugger, CLS extension and all of them give me a GOOD score almost no CLS is recorded

the problem is that inside Search -> web vitals ( desktop ) console pages are marked in red with POOR because a CLS issue

Any idea on hot to debug and fix this

Without more details, it is hard to be exact. The usual culprits of CLS are

  • Delayed loading of images and videos and they don't have the size specified
  • Slow loading of Fonts
  • Dynamic content added by javascript
  • Layout changed by CSS and javascript
