Update, this morning I selected Pre-release update in Software sources on my 15.10 install in Virtualbox, and after doing the partial update the animation works when the launcher is hidden.
Unity version is 7.3.2 on both installs (raw metal and virtual). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1439236 Title: When minimizing window, or for urgent events, the icon from the hidden Launcher doesn't reveal Status in Unity: Confirmed Status in Unity 7.2 series: Confirmed Status in unity package in Ubuntu: Confirmed Bug description: When the launcher is hidden and one minimizes an application window, the icon of that application shows up for a moment, hinting where is locatad.
