Unfortunately it looks like the only way to get this to work is to fake it. If you knew what content was to be underneath, you could manually apply the effects yourself using Win2D or D2D. However, that solution is imperfect and imposes constraints on what can be placed underneath the effect area without breaking the illusion.

The issue is that WPF composes all of its content into one surface. From the perspective of the system compositor, there is only one bitmap that we see. As such, we can only compose dcomp/WUC content above or bellow that bitmap. This is sometimes referred to as the "airspace problem".
If you could separate the content that is supposed to be "above" and "bellow" the visual, you could make this work. Unfortunately, I don't know off the top of my head how to achieve this in WPF.

So there is no way to do this. In .NET 4.5 they have introduced two properties to fix this aerospace problem, but it has been removed on the next releases.
1.3.10 Windows Presentation Foundation (WPF)
1.3.10.1 HwndHost feature has been removed from WPF in the .NET Framework 4.5 Beta
The .NET Framework 4.5 Developer Preview included a WPF HwndHost redirection feature. However, this feature had several known issues and has been removed from the .NET Framework 4.5 Beta. It will not be included in any future releases.
To resolve this issue:
No workaround is available.
