It looks like its a rounding error with the texture filtering. Which is not your fault.
If you turn off the texture mask by replacing the 4 with a 1 in the load texture, it comes back.
This is due to the filtering rapping around the texture. If you had a double pixel green line around all the text, I doubt if you would have noticed it. So get rid of the green and you should be fine as all the letters have a border around them anyway.
