Also on 14.04. Started googling for this issue once I noticed in Windows I did not suffer from this issue. Until that point I thought the mouse was just broken (some cheap Logitech mouse with USB bluetooth receiver).
Easy and safe test in gnome-terminal: nearly everytime the mouse moves to right/down direction, either of the first two entries get clicked.

Depressingly old bug report.
