Leaflet map loading half greyed tiles - coffeescript

Question

I have a leaflet map in a div that I loa like this:
<script src="http://cdn.leafletjs.com/leaflet-0.4/leaflet.js"></script>
<!--[if lt IE 9]>
<script src="//html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.4/leaflet.css" />
<!--[if lte IE 8]>
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.4/leaflet.ie.css" />
<![endif]-->
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
I then have a div such as this:
Some js that loads the map:
map = L.map($attrs.id,
center: [40.094882122321145, -3.8232421874999996]
zoom: 5
)
L.tileLayer("http://{s}.tile.cloudmade.com/57cbb6ca8cac418dbb1a402586df4528/997/256/{z}/{x}/{y}.png",
maxZoom: 18
).addTo map
Then on page load I have some JS that monitors window height and resizes:
$("#map").height($(window).height())
$(window).resize(_.throttle(->
$("#map").height($(window).height())
, 100
))
However when the map loads it loads with half the tiles in grey. When i resize the map loads fine but the initial load is 1/2 grey

Answer 1

If you don't have a reason to use JS for map sizing its probably better to use CSS:
html, body, #map {
width: 100%;
height: 100%;
}
However you can try using map.invalidateSize() after inserting the map into the DOM (or map resized by $("#map").height($(window).height())).
invalidateSize() is called by default when you resize the window, see the following links:
https://github.com/Leaflet/Leaflet/blob/master/src/map/Map.js#L609 and https://github.com/Leaflet/Leaflet/blob/master/src/map/Map.js#L616.

After a long search on this issue, in my case I had a global css style which was :
<pre>
img {
position: relative;
display: block;
max-width: 100%;
}
</pre>
In my case problem were the "position : relative", so I add a line
<pre>
//Fix personnal bug leaflet
.leaflet-pane{
img{
position: absolute;
}
}
</pre>
