So I'm having an issue utilizing the compare feature in Notepad++ after recently upgrading to Windows 10. The spacing between lines is slightly off to the point that by the time I'm down to line 11 on the left view, it's only at line 10 on the right view and it's extremely aggrivating. Here's a screenshot to show what I mean.

Follow the black lines and you'll note how it's off, starting small but becoming increasingly more spaced out :(
It seems the zoom setting is different for the views. Use the Menu: View, Zoom, Restore Default Zoom in both views.
