Bug Description

1. have two firefox windows opened
2. minimize one
3. get the other one focused
4. click on the firefox icon in the launcher to scale them
   -> the minimized window is scaled, but its content is blank.

Minimized windows are missing their contents in the Super+W window spread. The window decorations are there, but the contents of the window appear blank white.

I'm using the Oneiric proposed channel, so it might have something to do with the latest updates to Unity or Compiz.

The latest fix works well here with nvidia
(Did seem to introduce a very minor sometimes glitch when using spread with windows like nautilus, firefox, ect. A small white line can show momentarily below the window deco in one of the windows, doesn't happen all the time & quite easy to ignore

After last update, Unity 5.10 installed the problem persists for me.

Open several applications (thunderbird, google chrome, nautilus, etc...)
minimize google chrome to unity launcher.
trigger expo mode 'super + w'

chrome window appears as a white square in expo mode.
