Since the SRU has been filed now, I will close out the oneiric task as
the patch has already been uploaded there.


** Description changed:

- Binary package hint: xserver-xorg-video-ati
+ [Impact]
+ Garbage appears on screen when rotating the display.
  
+ We've had a number of reports of screen corruption with -ati esp.
+ relating to compiz/unity that is degrading experiences or making ubuntu
+ unusable.  This patch may fix many of these issues, where the user has a
+ rotated display.
+ 
+ [Fix]
+ A patch cherrypicked from upstream's tree resolves this bug, as confirmed by testing the package in a PPA.
+ 
+ The patch has already been uploaded to oneiric.  No bug reports have
+ been filed since that time (about a week ago).
+ 
+ [Test Case]
+ On affected hardware, with compiz or gnome-shell running, rotate one of the displays.
+ It should display properly; due to the bug it will display static garbage.
+ 
+ [Regression Potential]
+ Pageflipping is an optimization.  Thus, with this disabled, users with rotated screens may see some small performance loss such as tearing or flickering.  However, this is preferable to displaying garbage.
+ 
+ [Original Report]
  On natty, Running xserver-xorg-video-radeon 1:6.14.0-0ubuntu4
  
  I have a 1680x1050 display and a 1440x900 display. I'm trying to get the
  smaller one into portrait mode.
  
  It works fine normally, but with compiz or gnome-shell (and xcompmgr iirc), the
  smaller display (whether it's primary or secondary) just looks like static,
  that varies a bit based on what's getting displayed on either.
  
  Screenshot looks normal.
