Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager) [original description below] I get crashes, when I open a new window in an already started application. It happens irregularely, but I can force the crash if I open several new message windows in thunderbird. But it also happens in other applilcations, for example a new terminal window.
