This bug persists for me in Ubuntu 13.04 with:
unity-greeter: 13.10.3-0ubuntu1
nvidia-319: 319.32-0ubuntu7
I have the Nvidia GTX 295. I also use an SSD like Sapsan, though I don't know
if that is relevant.

Bug description:
[Impact]
After login, it's very possible the screen will appear corrupted and show
artifacts of a previous session. This is a security and privacy concern.
[Test Case]
Simple as logging in several times. It's highly reproducable (over 50% in my
tests).
[Regression Potential]
Seems low. We had this same patch in 12.04, but it got accidentally dropped
for 12.10.
[Original Report]
With the latest updates im getting corrupted graphics - images after the
login until the unity launcher - desktop appears and this is happening in
every system restart - relogin.
Im attaching a screenshot of what im getting , it looks like its a
combination of corrupted images from the windows that was running
while i was doing the latest updates , my last session before the
problem.
