Interesting. I don't see that effect.
Would you mind providing a short step-by-step so I can repeat your tests
here and see what happens? I'll try both with Glass enabled and disabled.

I'm pretty sure that means that Vista thinks that the app that's running
is incompatible with the Aero Glass user interface effects, and it is
turning them off while the application runs. I've only ever seen it with
Direct3D 9/8/7/etc apps that want to take exclusive control of the video
hardware.
I turned Glass off pretty quickly on my Vista setup, so I wouldn't have
noticed this issue. I'll enable it and do some testing to see if I see
similar results.
IIRC you might need an executable manifest that specifies Aero
compatibility, or to use different APIs to access the LUTs. I haven't
had to deal with this myself, though, so that's really just hearsay.
Here's some general information on the topic:
