Mac Minimized Minecraft Icon Lower Resolution

Minecraft, Since i can remember, on macs, the minimized icon has a lower resolution than the normal application icon , but it is just sightly noticeable , But now, with the new snapshot...
It's just ridiculous.
I put 3 screenshots here, the 3rd one are the normal old and new launcher icons ( the same )
The 2nd one is the old , from 1.5.1 to older versions minimized icon
The 1st and last one is the new snapshot minimized icon

Edit: The Snapshot one is not the minimized version , I've just noticed, It's the main icon , the application itself after the launcher opens the real game, It's the real game's icon , making it even worse, I can't believe it
