Hidden full screen slider image is downloaded on phone

I’ve dig into this further today and it seems it enabled on mobile “Inspect” even it is disabled in Responsive tab.
Is this a bug or why this slider/image is being fetched/referenced in code when it is disabled in Responsive tab?

<li style="background-position: center center; background-image: url(&quot;https://www.nebojsaarchitekta.sk/wp-content/uploads/2022/10/obyvacka-architekt-design-5.jpg&quot;); visibility: visible; opacity: 1; transition: none 0s ease 0s; transform: translateZ(0px);" data-img-url="https://www.nebojsaarchitekta.sk/wp-content/uploads/2022/10/obyvacka-architekt-design-5.jpg" class="avia-slideshow-slide av-la3o7zdp-7c7a12052fe9ac8d535f4a735eaf459c__0 av-single-slide slide-1 slide-odd next-active-slide active-slide"><div data-rel="slideshow-1" class="avia-slide-wrap "><div class="av-slideshow-caption av-la3o7zdp-7c7a12052fe9ac8d535f4a735eaf459c__0 caption_fullwidth caption_center"><div class="container caption_container"><div class="slideshow_caption"><div class="slideshow_inner_caption"><div class="slideshow_align_caption"><h2 class="avia-caption-title " itemprop="name">interiéry od návrhu až po realizáciu</h2><div class="avia-caption-content av_inherit_color" itemprop="description"><p>váš domov by mal rozprávať príbeh o tom, kto ste a súčasne byť zbierkou všetkého čo milujete</p>
</div></div></div></div></div></div><div class="av-section-color-overlay" style="opacity: 0.1; "></div></div></li>

Thanks Ismael,
Didn’t know this.

Additional questions:
1. Is it possible somehow possible patch this css code for mobile with different url (so it won’t download anything). The main thing I want to achieve is to force Enfold to not download that image (or download some different 1kb one) on mobile platform.
I’ve tried something myself but was not able to adjust URLWITHIMAGE part of below code. It seems it is some element.style which I have no clue how to adjust using CSS.

element.style {
    background-position: center center;
    background-image: url("URLWITHIMAGE"); 
    visibility: visible;
    opacity: 1;
    transition: all 0.4s cubic-bezier(0.55, 0.085, 0.68, 0.53) 0s;
    transform: translateZ(0px);
}

2. I also have different slider gallery on homepage for desktop which is hidden for mobile, but those images are not downloaded. Is it configured differently for that gallery?

jfyi: As workaround I found a way to have separate page for mobile view where this component is not added. However I would like somehow 1. to apply.

function redirect_mobile_devices() {
    if ( wp_is_mobile() && is_front_page() ) {
        wp_safe_redirect( get_site_url(). '/home-mobile', 301 );
        exit;
    }
}
add_action( 'wp', 'redirect_mobile_devices' );

Thanks
Jaro.

Thanks Ismael for closer view on this. I hate redirects as it slows stuff so still trying to figure this out.
I found this old thread on forum from 2017. Do you think it could be applicable here?
https://kriesi.at/support/topic/enfold-background-image-remove-on-mobile/

The code part there suggests to add custom ID, adding function and then applying CSS. I expect some stuff to be outdated in script (f.e. .av-paralax)? I’ve also hit issue with using it “Uncaught ReferenceError: jQuery is not defined”

function remove_bg(){
?>
<script>
jQuery(window).load(function(){ 
	if (jQuery(window).width() < 768) {
		jQuery("#unique-id").css("background-image", "");    
	} 
});
</script>
<?php
}
add_action('wp_footer', 'remove_bg');

+ then css change

@media only screen and (max-width: 480px) {
#unique-id > .av-parallax {
    background-image: none !important;
}}

Just want to be super sure if something like this could work with minimum effort to adjust or I would need to figure this out somehow from scratch.
Thanks

Thanks Mike,
I’ve tried this code but no luck. At least seems to have no effect.
When I checked the console output I’ve got following:

(index):137 Uncaught TypeError: Cannot read properties of null (reading 'parentNode')
    at removefullscreenSlider ((index):137:26)
    at (index):141:1

Can you please check what might be causing this?
I’m testing this on following page (private data)
Thanks in advance

Thanks a lot Mike for getting this resolved,
This seems to work perfectly and no more complains about big image being downloaded on mobile phone. I’m sending some love for this :)
Feel free to close this out.

Jarol
