In OpenLayers 2.12, the backbuffer for each layer was placed right below the layer itself. With animated zooming, that was changed so backbuffers are all placed below the base layer. As it turned out, this is only good for certain kinds of layers (e.g. street labels), so the default now is to place the backbuffer right below its layer again. But the transitionEffect option can now have a new value, 'map-resize', which will cause the backbuffer to be placed below the base layer.
