How to disable transparency for the project navigator?

Question

I've updated to OSX Yosemite and see that one of the new "features" of Xcode is blur/transparency effect for the project navigator window. Below is an example of my wallpaper blurring through. I find this to be really fugly and distracting.

Is there a way to disable this blur effect and get a flat/opaque Xcode 6 window?

Open System Preferences > Accessibility > Display and select Reduce Transparency.
