Comment 85 for bug 676166

When resumed from sleep, the launcher bar at the left appears corrupted. Simply mousing over will redraw it, no bid deal. This has been reported by many users already.

Another interesting artifact is the window "shadow". The darker zone undernearth windows is not completely black, but filled with garbage data or even sometimes content of a web-page I closed earlier.

Using various nVidia drivers (current, port-release or edgers) leads to the same results.

Using Unity 4.22.0-0ubuntu3

Let me know if I can be of any help and thanks in advance for your support.
