Newly opened windows appear behind the Unity panel and launcher

[Alistair Buxton]

Steps to reproduce:

1. Open any window of any application.

Expected result:

The whole window is visible.

Actual result:

The window is obscured by both the launcher and top panel, regardless of what size it is. All new windows appear at position 0,0.

Impact:

User can't move or close windows unless they know to hold Alt and drag the window.

This is a recent regression.

I can not reproduce. Please try a fresh live usb if you can reproduce.

It seems there is something going wrong with compiz with your machine. What happens when you run `compiz --replace` from terminal?

[Alistair Buxton (a-j-buxton)]

compiz --replace has no effect.

It works correctly in a live USB.
