Actually when my smoker arrived originally the middle section was so bent up I couldn't even come close to getting the lid on, and I contacted Weber and they sent a new middle section immediately. now the top fits onto it just fine BUT now I am wondering if despite that I still have issues per your comment.
I may try 1-2 more smokes, and if I keep seeing leaks out of the lid like this I think I will call them and at least ask what they think may be the issue. I didn't realize it shouldn't be leaking out of the lid (outside of obviously the vent part)
My lid leaked exactly like that picture. Gasket kit solved the issue.
Also, the lid may seal after 10 or so smokes. Understand though, as bad as mine leaked, I smoked anyway and made great Q. Mine never sealed so I took care of it with a quick fix.
