Bad loading images of gallery in mobile devices

You can see jumping images of gallery in the video: https://predajsvojpribeh.sk/jumping-images/
The same issue is in the slider of Sydney FP: Latest News - B.
This concerns only mobile devices.
Issue on the site/home page:https://malujemeke.sk/
Thx for help.

I tried Opera also. The same issue. :frowning:

Hello Peter,

I’ve just checked your website in Chrome on iPhone 7 Plus and it scrolled smoothly, have you already resolved this issue or your device is still affected?

Kind Regards, Roman.
