Public bug reported:

I found a critical bug in compiz, the x-window-manager.

Ubuntu version : 12.04.4 LTS
compiz version : 1:0.9.7.12-0ubuntu3

The test case is as below.
1) Set the window placement option to cascade mode.
- run "gnome-terminal" and then type "sudo gconftool-2 --type int --set /apps/compiz-1/plugins/place/screen0/options/mode 0"
OR
- run "gconf-editor"(At first, install "gconf-editor" from software center) and then go through " /apps/compiz-1/plugins/place/screen0/options/" and the set "mode"value to 0

2) Run "gnome-terminal" and then repeat opening new windows about 30 times.(using shortcut key <Ctrl+Alt+T>)
(OR run "nautilus" file manager and then repeat opening new windows about 30 times (using shortcut key <Ctrl+N>))

It is Note for you: Although you reproduce this bug, your Ubuntu will not break. System restore is very simple. Please try log out and log in again. And then try resetting as following.
run "gnome-terminal" and then type "sudo gconftool-2 --type int --set /apps/compiz-1/plugins/place/screen0/options/mode 2"
(OR - run "gconf-editor"(At first, install "gconf-editor" from software center) and then go through " /apps/compiz-1/plugins/place/screen0/options/" and the set "mode"value to 2)
