Hi @svitus,
I looked into your site i.e https://www.riparazioniinfissi.roma.it/ and most probably you have added the below code in your customizer CSS which was previously suggested by my colleague, please remove that.
#parallax-bg {
background-size: 100%;
}

In another context @svitus @klxhzm @albow44 @lauralsweet, our team sat down and talked about this topic and came to conclusion that the header image have a parallax effect and it’s intended to display images that aren’t textual or informative images which seems like it’s not responsive in mobile view.
I’ll like to inform you that it’s not an issue that needed fixing so it won’t be included in our upcoming update.
Thanks and Regards,
Milan.
