["D. Charles Pyle" <dcharlespyle@xxxxxxx>]

I am seeing the same things as reported above, and I am seeing this in
14.04 LTS.  I switched to fglrx to try to get rid of the corruption and
still saw it, although it was less than while using the Open Source
drivers for AMD/ATi.  Tearfree created other problems so I went back to
Open Source.  Now the video corruption is back again, and sometimes it
includes bits of desktop from a previous session even after a reboot.

I even tried switching to another ppa to get the latest and greatest
versions from git and still see the corruption while waiting for the
greeter to be ready for logon, and between greeter screen and logon to
desktop, as well as when I log off and wait for the greeter to return to
ready.

ASUS/ATi Radeon HD 5750, dual head with a pair of Dell S2440L LCD
monitors.  Ubuntu 14.04.2 LTS.

Wanted to try the above workaround but this system does not use GDM, so
no directory or files on which to do the same edits.

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.
