Comment 32 for bug 886605

I also still observe this problem on at least two up-to-date Ubuntu 12.04 machines. Can be also worked around by restarting compiz (compiz --replace).. didnt try Eduards workaround in post18 in the following link: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/958353, but will do so the next time this happens to me. unity version is 5.18.0-0ubuntu2 and compiz is 1:0.9.7.12-ubuntu1. pop-up notifications like gmail chat in chromium will also show up in locked sessions.. so theres definitily a pretty heavy information leak..
