Red Hat: Updated compiz packages prevent Compiz from breaking screen saver

Compiz is an OpenGL-based window and compositing manager. Most screen savers create a top-level fullscreen window to cover the desktop, and grab the input with that window. Compiz has an option to un-redirect that window, but in some cases, this breaks the grab and compromises the locked screen. Fixed packages are available from updates.redhat.com.
