Тормоза после обновления до xorg-1.6

Вчера обновился полность (emerge world -Du), делаю это примерно раз в неделю.
Прошло обновление XOrg с 1.5 до 1.6.
Конечно же провел revdep-rebuild.
После перезагрузки X-сервер стал работать ужасающе медленно. Это сказывается на прокрутке страницы в FF и пр.

Был включен compizite в metacity, отключил - немного отпустило, не не существенно.
