This sounds great but this is not the solution I have come up with.

I think compiz is in fact the very model example of what a compositing
manager for the Linux Desktop should be. Yes, it has had many bugs
over the years but many of these are because the X protocol is
extremely difficult to work with and inherently problematic. We can do
the same things now, but this time, uninhibited, thanks to the driver
situation. I am sorry that you feel this is unnecessary but I
disagree.
