Is your feature request related to a problem? Please describe.
MacOS has support for the vibrancy field, there's been quite a few Windows versions, yet there's still no official support in Electron.

Describe the solution you'd like
An official Windows solution to vibrancy, using acrylic or any other background blurring method.

Describe alternatives you've considered

All require a lower version of Electron than 4.0, and/or to be building on Windows.
