Comment 5 for bug 998289

The installation in question was fully updated and used nvidia-current versions 295.40 and 295.49, available from the Ubuntu repositories and my PPA, respectively.

This machine has been migrated to a virtual environment. But, it still exists with a fully updated machine using virtualbox 4.1.18 and guest additions version 4.1.18. See the newly attached image.

It seems to be more easily reproducible by launching the application for the first time, minimizing the application, and then maximizing it again by clicking on its icon from the Unity panel.
