I am experiencing the same issue described above: text in notes appears fuzzy, exactly as in the screenshot provided. I am using Evernote 6.22.1.8767 (308767) Prerelease. Have been experiencing this issue for about 2 months now but it has become progressively more frequent. Closing Evernote completely and re-opening provides a temporary fix (for a few minutes), then the text becomes fuzzy again.
