moving application between desktops does not redraw on new desktop

Holding shift+ctrl+alt to move thunderbird to a new desktop does not repaint thunderbird after having moved to the new desktop.

Clicking on the thunderbird icon in the unity dash does not cause a repaint of thunderbird. Only moving to another desktop, and back again will cause thunderbird to draw.

Other applications do not seem to be affected *(nautilus, chrome, terminal, etc...).
