I have the same problem on Windows 8.1 and it has existed ever since I've used Evernote (several years). It looks the issue is that when scrolling with the mouse wheel, Evernote will always scroll the same amount in absolute terms (about 200px). This means if you're using 10pt Courier New it will scroll about 13 lines per scroll click. Whereas if you use 48pt it will only scroll about 2 lines. However Window's vertical scroll setting (found in Mouse Properties in Control Panel) also affects Evernote. If the setting is set to 1 instead of 3, the distance decreases to about 75px, or about 4 lines at 10pt. On a related note, why is the framerate when auto-scrolling a note so low?
