So somehow a setting has changed in my Photoshop 2014 CC preferences...
The pop up boxes, like the layer styles window that opens after double clicking a layer, look different to how they're meant to.
See attached images below.
I can't see any obvious settings in Preferences > Interface that would affect this.
How do expect them to look?
The ones in photoshop cc 2014 have a more grayish look than previous versions of photoshop.
