Found a New Error ;)
To Reproduce: - Click and Drag a Rectangle from one Stage over to the 2nd one..
and Release the mouse. Move the mouse around and try to click in the 2nd
Stage.. and watch the following error come up.
(GTK2:5330): Clutter-WARNING **: The required ID of 8421504 does not refer to
an existing actor; this usually implies that the pick() of an actor is not
correctly implemented or that there is an error in the glReadPixels()
implementation of the GL driver.
Here is the updated code to test.
