For Saucy, I've been using the 319 driver from Ubuntu - https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-319. In my tests with 14.04, I kept the Nouveau driver installed; the same is true for my tests with 12.04.2, which I used the Nouveau driver for. The bug is reproducible if I use either driver.
