** Description changed: Some little horizontal black lines sometimes appear on the Ubuntu desktop. They disappear quickly, and there seems no obvious way to force the event to occur predictably. The problem occurs with libgl1-mesa-dri-experimental but, unless I'm mistaken, occurred also with the nonexperimental branch. Furthermore, I'm running Ubuntu Classic and was not using 3d effects when the problem occurred (was simply typing text in LibreOffice).
