We need a Flawless Widescreen profile for S:SE, but it's hard to tell when (or if) HaYDen is going to release one. He may be waiting for the script extender and the full SkyUI mod to be updated (?) since he had to add support for SkyUI in the vanilla Skyrim FWS profile. This is complete speculation on my part of course. There isn't even a dedicated WSGF page for S:SE yet as far as I can tell, and I haven't found any comment online about any of this. At the very least, I think we're in for quite a long wait before the UI is fixed via a FWS profile. For now, S:SE is pretty much unplayable (at least for myself personally) with the UI rendering offscreen on the top and bottom.
