Comment 26 for bug 1310823

Played around with Unity/Compiz (moving windows, opening dash, etc.) while running 3.13rc1 to make sure the bug is triggered. And after a suspend it didn't come back. This leaves us with 3.12.19 being the last version which is known for working fine, and 3.13rc1 is the first version which is buggy. This is not a great news as it means there is a lot of new code between 3.12/3.13 series; narrowing down should be quite hard.

Unfortunately I don't have the skills to do the bisecting thing and no time to learn it at the moment.
