Fix: Blurry fonts on some LCD screens

Fix

Some users have contacted support that things are a little blurry on some screens. This is hopefully fixed by this change. I am unable to reproduce therefore unable to test to ensure that this works.

Fixed blurry fonts on some LCD screens

I can't repro the issue either, but it's pretty straightforward and the fix is recommended by the docs. Nothing weird shows up for me in testing so I say

(I tested with the Mac font smoothing setting turned off on my external monitor, but I think this that thing that only happens if you don't have a retina screen.)
