Is there any way of creating a NSWindow that has a semi-transparent, blurred background? With "blurred background" I mean that whatever you see through the window/background is distorted (blurred).
There isn't a particularly fast way to do this, although I have experimented with it a bit in the past. You can use the CGWindow API to read the contents under your window and apply a blur to them using Core Image directly or indirectly via Core Animation, but in either case you'll see the Window Server spending considerably more CPU time as it has to re-render the contents under your window. You could fake it by updating the image rarely but there isn't a particularly good way to completely mitigate the CPU usage.

In 10.5 you can add any core image filter to a window using the private function 'CGSAddWindowFilter'.
Please do not use private API, they are subject to change in ways that can break your application on any OS update. File a feature enhancement request describing what you wish to do instead.
