STR: 1) Open "Social" smart collection (or whatever) 2) See how the content is translated some pixels when all icons are rendered and the scroll detects it Video attached to show the issue ----- https://github.com/mozilla-b2g/gaia/blob/master/apps/collection/view.html#L79 Notice that <gaia-grid> has not height because all the content is translated with transformations. The issue disappears if I add this here https://github.com/mozilla-b2g/gaia/blob/master/apps/collection/style/css/view.css#L1 height: 1000%;

Vivien, should I move this to Zoom&Pan component? or any suggestion is more than welcome

But it breaks the offline case. Seems much more a css issue related to the usage of flex than a pan/zoom issue to me.
