Windows 10 version 1803 adds translucency to some UWP apps, including title bars.

Is there API to get use this translucent title bar in Win32 apps?

(I know about owner drawn frames, that's not what I'm asking for. But I am totally open to nasty hacks involving Windows Runtime APIs.)

    [Acrylic material](https://learn.microsoft.com/en-us/windows/uwp/design/style/acrylic) for UWP applications. I'm unaware of a Windows API call that produces the same effect on a native Win32 window. – IInspectable May 02 '18 at 10:43
  • UWP leans pretty heavily on DirectComposition. This smells like IDCompositionDevice3::CreateGaussianBlurEffect(), hard to be sure from a screen-shot. – Hans Passant May 02 '18 at 11:26

  • That does seem to be it @HansPassant, good answers there too. The title bar issue itself is only shortly addressed but there are some pointers. – Sijmen Mulder May 02 '18 at 11:46
  • Since Windows 8 [I use this DLL](http://www.glass8.eu/download) to restore the Windows Vista/7 Aero Glass for title bar. – magicandre1981 May 02 '18 at 15:18
