Comment (by TomH):

 Yes I looked at this last night on the main site and I'm pretty sure it's
 an OpenLayers bug. My best guess is that it relates to this code:

 https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Layer/Grid.js#L469

 which as you can see from the comment is supposed to force a retile when
 you warp from one side of the world to another.

 What you will see if you look at a failed case is that the tiles are
 positioned at massively crazy offsets in the back buffer - hundreds of
 thousands of percent and things. Zooming out or changing window size will
 cause a retile and fix it.
