Reveal image no longer working on live site

Hi Shiri, Jeroen,
I see this post is from January, but I seem to have the same problem lately,

I am designing my website, and have been experimenting with “reveal” image scroll effect for a while. It used to work perfectly, till yeserday.
This is how it looks on chrome (updated regularly):

The thing is: it works perfectly on Microsoft Edge:


And on Safari (iPhone&ipad)

I have older experiments with the reveal effect from about half a year ago, and they all worked perfectly everywhere till yesterday.

I have some published EditorX sites that work perfectly on my chrome (though they only use parallax - not the reveal effect)

This is the temporary site:
https://koomkoom.editorx.io/7607
Only a very rough WIP beginning.

I suspected the problem is local chrome on my machine:
cleared all wix’s cookies, cache, disabled extensions, disabled anti virus & firewall for a while. But the problem presists.

When I ctrl+refresh the images in between - another image is loaded - but the second one disappears.

Is there a solution for this?
Thanks
Gidon
