It looks like he’s been working on it. I did see he mentioned something about another update coming soon, so that will probably be one of the fixes. I looked at the demo and it currently fills the entire screen.
This is the code you were referring to…..which seems to be fixed and different than what’s in 1.1.2 (which is why I assume he’s making an update to that part) –
.front-page-1,
.front-page-4,
.front-page-5,
.front-page-7,
.front-page-9,
.front-page-12 {
/*background-attachment: fixed;*/
background-position: 50% 0;
background-repeat: no-repeat;
-webkit-background-size: cover;
-moz-background-size: cover;
background-size: cover;
}
Changing the background size to cover
seems to do the trick for larger monitors.
