Comment 5 for bug 787814

I am running linux mint 11 and also have this problem. I'm fairly certain the problem is that the opacify settings aren't applied ot new windows. If you turn opacify on and off, it works, but when you open a new window, opacify only works for the previously opened windows, not the new one.

There's a screenshot attached to my post, to demonstrate what I mean.
