Thank you fore response,

On live site – yes it is an outdated version. We transferred site to dev site so we can troubleshoot, and it is on latest version and still happening.

Thank you for your answer.

Can you see it on the live site? https://deeforeman.com/gallery/

If you cannot replicate it on your site, maybe you can see what is happening here on live site. If you do see it, what do you suggest other than basic troubleshooting that we already did.
We disabled every plugin/function/theme/child theme etc… so on and it is still happening.

What can be the cause of this?

Thank you for reply, but we already did that.
Even on twenty-seventeen theme.

It is happening when we setup to be 2 columns of images on mobile devices.
Since it is a masonry gallery we used

-webkit-column-count: 2;
-moz-column-count:2;
column-count: 2;

Can you tell me why is this causing so much trouble?

or exclude this for certain pages?
