Please someone-else test this with some heavy CPU, Java and OpenGL applications like the Minecraft Client.
Unfortunately I am unable to test this with Unity or without Compiz.
As a visually impaired, I strongly depend on the Compiz eZoom feature witch does not work properly with Unity and the menus with unity are too far away of window content for appropriate use in a zoomed environment.
I spent to much time re-establishing eZoom's mouse wheel commands and decent mouse tracking with CCSM because that where reset by upgrade to non-working. Having to repair all the mess without eZoom require some tier help.

Title:
  Screen locking let show screen content before password dialog

Status in “gnome-screensaver” package in Ubuntu:
  Incomplete

Bug description:
  Using classic desktop and compiz. If the session get auto-locked during screen-save, moving the mouse turn off the screen saver obfuscation and bring the screen visible to unauthenticated user without any password prompt.
  It is only after issuing a mouse click or some keyboard event that the screen goes black again and the password unlock dialog appears.

  This bug may allow unauthorized users seeing screen content and
  possibly use the session before the password dialog fires-up.
