OS X Yosemite DP3 Dark Mode

Just updated to Developer Preview 3 and activated the Dark theme right away!....but on a non-retina screen (2012 27" iMac) the fonts are super jagged as well as colour icons in the menus being extremely faded and pixelated compared to Light mode - Anyone else experiencing this as well?

When i turn off menu bar transparency with Dark Mode enabled the fonts are much clearer and the menu icons are as they should be, thoughts?
