What? It does too work! Once the window is setup correctly.
This is how a do all my transparent windows, and for any naysayers out there here is the code:

It is obviously not as simple as the two sudo lines of code I put there, but I was trying not write the damn things for him, and set him on the write path instead, as I'm sure with the Transparent window samples available on the net and in the docs he can manage to figure out how to setup the window and view for this to work, and now instead of him figuring it out (learning to fish), I did it for him and it took me all but 5 minutes using code I already had written (you made me toss him fish instead, just to show it CAN be done) :)
Filling a rect DOES NOT NUKE anything, you simply need to override the defaults which are optimized for rectangular non transparencies areas to make them faster. It's not that they can't its just faster not too, so that is the default.
