Still getting the "hidden lines" issue.
I glanced through the epub, and saw lots of very wide tables that are offscreen, even on my widescreen monitor. I looked inside, and it appeared that they were in table data and/or row tags, but without the surrounding table tags. It looks like a tables issue to me, although if you point to a particular non-table bit of text, I'm sure someone will look at it. I'd try linearize tables to make sure that doesn't fix it, and also check to make sure you don't have some malformed html relating to tables.
