Comment 83 for bug 467668

Hi Doug, Thanks for helping with the tests.
It is hard to get ultimate conclusions as you have a more complex setting with awn as well. It may be related to deeper bugs in the same direction, namely lack of backward compatibility in reading user's home.
Yet for most users who had enabled desktop effects, upgraded and now don't have windows borders, it may be inside .config or at most {.config,.compiz} as Rob's post suggests.
