launcher corruption after resume

[Thomi Richards]

After suspending and resuming may laptop, the launcher does not render correctly.

With the current packages in precise, the launcher is drawn as a multi-coloured mess.

With the ucrrent unity + nux trunk (unity revno 1972, nux revno 566), the launcher is drawn as a white square.

See screenshots of both below.
