The issue occurs when using Safari on iPads running iOS 13.1 and above to view websites built with the WordPress 2017 theme.
The issue does not affect iPhones using Safari or iPads using other browsers or running earlier versions of the iOS.
SITE OWNER WORKAROUND: See this post on the WordPress forum. Look for the comment by user PhillipPrem, copy the snippet of CSS suggested (also shown below), paste it into the Custom CSS area (Appearance > Customize > Additional CSS), and click Publish.
The code snipped is as follows.
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px) {
.background-fixed .panel-image {
background-attachment: unset;
}}
