I suspect this is an issue because we use a transitionEffect by default now,
which does not work for IFrame tiles. Can you please create a ticket on
http://trac.osgeo.org/openlayers ?
A workaround in the meantime would be to use tiled layers and configure them
with a gutter (e.g. "gutter: 15" instead of "singleTile: true").
