Description Penelope Fudd 2011-06-28 22:28:19 UTC
Description of problem:
I've got two users logged in via switch-user.  One user is playing Angry Birds on Chrome.  The other user is working.  The working user can see a bit of bleed-through from Angry Birds on his root window.

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.9.5-1.fc14.i686.rpm

How reproducible:
Not tried.

Steps to Reproduce:
1. Log in as user 'A', start chrome, download angry birds for free, play
2. Switch User, log in as user 'B'
3.
  
Actual results:
There's rows of pixels that are recognizable as angry birds artwork, repeating across user 'B's desktop.

Expected results:
Complete isolation between A and B.

Additional info:
It doesn't matter if angry birds is minimized or not, the artwork is still there.  See attached screenshot.  After switching back to A, the chrome windows was full of garbage, except for the small area where the birds were, to the left of the slingshot.  Also, the pixels are now embedded in my root window, since I closed chrome and logged out user A but the pixels are still there.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Comment 3 Fedora End Of Life 2012-08-16 16:38:02 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
