In windows 8/10 can you still use the 'glass' blur in overlays? I wrote a similar thing on top of XNA a few years ago and remember there existing a flags/clear color combination which made the background of the frameless window look like the blurry aero glass.

The start menu in W10 has that effect, so there must be still a way to do it?

Indeed, you can use the same effect as the start menu via the undocumented API SetWindowCompositionAttribute [1]. Note it only works properly with frameless windows, if you have a titlebar there are slight artifacts around the window.
