For those who are strugling with this bug hereby a CSS workaround:
@media screen and (max-width: 1024px) { // for tablet
selector div {
background-position-x: -20px !important;
background-position-y: 0px !important;
}
}
@media screen and (max-width: 767px) { // for phone
selector div {
background-position-x: -120px !important;
background-position-y: 0px !important;
}
}
