Yes, can confirm it is a high fps, I had the same problem and had it sorted but it started again! You may also get problems around running water in caves etc....
I'd solved it be forcing on v-sync via my Nvidia control panel but recently updated to beta drivers and the install had reset the v-sync to off, I just forced it on again and problem solved

Here's a link to the fps limiter if that's needed too: http://skyrim.nexusmods.com/downloads/file.php?id=34
Good luck, is very annoying having that Poltogous in all the inns!
