When enabling the ‘unredirect fullscreen windows’ option, compiz will unredirect fullscreen windows to improve performace. However, unredirecting will as a side effect break any grabs on that window, which compromises most screensavers. This X server update suppresses this unintended side effect and restores the security of the screensavers. See also CVE-2007-3069.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
