I have the same problem. Took my XP100 experimenting at the beach, after about an hour I had moisture under the screen. Annoying as the camera is brand new. Regardless the moisture for me didnt really affect the video quality. I took some pretty decent high frame rate shots. See here http://www.youtube.com/watch?v=zNkJPFwN7OA notice towards the end it gets blurry. thats the damn moisture.
