Unity Launcher draws garbage after waking from hibernation

[Henri Sivonen]

Binary package hint: unity

Steps to reproduce:
 1) Put the computer into hibernation.
 2) Wake the computer from hibernation.
 3) Move the mouse cursor away from the Unity Launcher
 4) Move the mouse cursor to the left edge of the screen to re-reveal Launcher

Actual results:
After waking up from hibernation, the screen region belonging to Unity Launcher draws garbage that looks like both the RGB and alpha values were an interpretation of non-graphical data or random uninitialized memory. When the Launcher is hidden and re-revealed, it draws correctly.

Expected results:
Expected Unity to detect that the OpenGL graphics state has been lost during hibernation and redraw Launcher upon wake-up.
