Hello kweb,
you need to set the background attachment to fixed.
Currently the attachment is set to scroll.
.sp-page-builder .page-content #animated{
background-attachment: fixed;
}
It should be possible for you to set this in the SPPB.
Unfortunately, I am currently on the laptop without access to the SPPB and can therefore not check whether and which setting would have to be changed.
