There was the same problem on Radeon and Intel boards. It is now fixed
upstream by implementing some clever zero-copy AIGLX things in the
driver. So no, it's probably not a bug in compiz, but much more some
performance requirements in the driver and server core.
We had some reports about compiz working well on recent nVidia boards.
Maybe your board is too old and requires the legacy nvidia driver, which
might not provide the required optimization for fast resizing with AIGLX.
