Arduino IDE, grainy text and icons on mac

I downloaded the official ide for arduino on my macbook, but the project name and buttons are so grainy.
How can i fix this?
The text editor itself is fine.
I attached a screenshot.

Im going to share some thoughts.. Im guessing the button images are not retina compatable?
But why is the text grainy and unclear aswell? Do they use a non standard font?
Does anybody else with a mac experience this?

looks just like my mac

Looks fine on my iMac...

Try downloading the newer version of IDE, it might fix the problem.. http://arduino.cc/en/main/software
