It sounds like you are experiencing this problem
https://bugzilla.gnome.org/show_bug.cgi?id=724788

The fix is a two line patch that is released against clutter 1.16,
but it applies cleanly against 1.14 (which is in CentOS 7, maybe this
gets fixed with the upcoming Gnome rebase).

I rebuilt the clutter rpms with the patch and the flickering problem
went away.
