Hi, I've some issue with the transparent window, my code is:

win = new BrowserWindow({
  width: 100,
  height: 50,
  transparent: true,
  frame: false
});

On Mac I have not any kind of problem, on my Windows 7 Parallels virtual machine again no problem, but on another pc (not virtualized) with Windows 7 transparent windows doesn't work (I have a white background).

I haven't error logs from console.
In both Windows 7 machines I have DWM enabled and running (in fact, both are using aero).
