I have the same problem and it is intensely annoying. Enough that I have started storing web pages by other means.
When I clip 'Article' or 'Full page' the article is unreadable in my notebook as I have to scroll right to the bottom to use the horizontal scroll bar.
Generally, it's only a few words that are chopped off on the right - but this makes the whole note unusable.
I can't see a setting to change this - I'm not sure when it started exactly. I am using windows - but I'm using the web clipper and viewing the notes by logging on to Evernote
