Mac OS X Native Fullscreen vs Minecraft Fullscreen on Retina Display

Minecraft textures blurry and low quality:

• Open Minecraft
• Enter Game
• Toggle Fullscreen (F11)
  Minecraft textures clear and high quality:
• Open Minecraft
• Toggle Native Fullscreen (Green Button, left corner)
• Enter Game

With a good eye you can easily spot the difference, on a 5k Screen they are very noticeable.
