Thanks for posting the videos. That helps clarify (heh) the problem. Actually, it doesn't look to me like there is a problem; that's just the font and style that Evernote uses, for some incomprehensible reason, for annotations. I'm attaching a few samples, both PDF and JPG, from the annotation window and as annotated. They look just as blurry as yours. Objections to this font have been raised here, with good reason, IMHO: it looks unprofessional, unless your profession is kindergarten teacher, and takes up too much space.
