Taking a screenshot is not working properly in LM 14 'Nadia'

[Rafael Belmonte]

When I take a screenshot, the captured image does not fit the current screen image/state, it captures an old screen image instead.
This computer uses the AMD fglrx restricted graphics driver.

Steps to reproduce the bug:
1) Start Linux Mint 14, and use it during a few minutes.
2) Take a screenshot (you can use any of these methods: Keyboard key, Gimp, gnome-screenshot).
3) Take a look to the captured image or to the saved file.
4) You will note that the captured image does not fit the screen state at the momment it was created, it contains an image of a previous state.

--What is happening now?
You will note that the captured image does not fit the screen state at the momment it was created, it contains an image of a previous state.

--What is the expected behaviour?
The captured image/file should represent the screen state at the moment the screenshot was taken.

I forgot to mention that this is using Cinnamon desktop.
