What if we not only define the region to apply the effect to, but also receive a shader to go along with it?
Today I found out about ShojiWM, it can apply shaders to windows, also on windows events.

That way, the app developer can control the transparency effect - be it blur, or refraction or anything else, without the ability to capture the background picture.
