Hi, I have found in the Google Console a new warning about CLS - cumulative layout shift. Briefly, the issue is reffering to sudden and unexpected layout movement during navigation, at least Google tell this.
Clear is not a problem of end user of Website X5. Does anyone have a clue?
The whole description is here and most of the pages are affected:

Marius, there are a number of pre-existing posts about this issue, but apparently no specific fix. If your problem is reported as on every page perhaps it is in the header or footer? Can you provide a link to your site to see if anyone here can identify the problem?

Hi, I am sorry for didn't found the previous topics abutthis issue. I am glad the the developer team is aware of this and I am sure they will fix it.
Regarding my website it is about http://www.softedu.eu
From all pages Google told me that a halph are affected. Maybe they are affected all but the crawl did indexed only a halph.
Anyway I have checked yesterday "fix validation" and today the errors are ... fixed. They will appear again next week or month as Google practice.
Now the only page still looking with errors is: http://www.softedu.eu/curs-autocad-lt.html but maybe are indeed all affected we will see this on the next bot crawl.
The same issue could be found on "content larger then screen". My content is not larger and I always just checked "validate" and I found them valid.
First of all I am wondering how reliable is this Google warning. But relaible or not it does affect our pages.
Marius, the fact that Google only identifies this problem sometimes indicates to me that it may not be a problem at all. I can see no issues visually.
I have a number of websites that have not been modified for years, and yet at random Google reports problems. I make no change, tell Google it has been fixed, resubmit and clean bill of health.
I suspect my hosting fails to serve content in a timely manner occasionally

Indeed this is my feeling too. Let's wait and see the next "warnings".
