It's also happening now with Firefox as well (in fact, Firefox is virtually unusable) so I suspect there is something happening with either this machine or the OS.

Are you running the proprietary NVIDIA driver? (either the one from elrepo OR manually building from the NVIDIA site)

If so, the recent xorg-x11-server updates require that you rebuild (or reinstall) the drivers as those drivers replace some xorg files and if you do not reinstall it can freeze the system or crash X.

If you are having issues with the Nvidia driver under CentOS 6.5, the first thing you may want to try is to run:

yum remove xorg-x11-glamor

(See http://lists.elrepo.org/pipermail/elrepo/2013-November/002058.html if you care about the details. :-)
