I don't understand how a confirmed bug can get expired for lack of activity these many times. This is a problem in multimonitor Xinerama setup, that appears when the the launchers are set to autohide. This happens in Unity-2D, not in Unity proper, we are forced to use Unity-2D, because it's not possible to use Unity proper with this setup.
When the launcher is not in autohide, the mouse scrolls fine, to the expected part of the screen. When it's in autohide, however, the mouse appears on top of the launcher when it should appear on the other edge of the screen.
