Comment 2 for bug 1218360

My de is gnome 3.4 and i'm using Ubuntu 12.04 lts.

Cario-dock version is 3.0.0 and the dock is located at the right side of the screen.

Bug is not depends on if windows is maximised or not; it can always be reproduced but it happens when i move cursor along the area vertically for maybe 1-2 pixels, it does not becames visible after just hitting the midpoint. But when window is not maximised, the area slips through the window's vertical position.

I'm adding a screenshot.
