Well, I rally tried to identify the cause of this problem but with no success. There isn't a pattern. Anyway, I'm almost sure that is the video driver because of the following: one thing I forgot to mention is that, as a workaround, when the system is lagging I press the "Super" button to open the dash and the system stop lagging. It seems that it is a composite/driver/3D issue. Using other desktop environment like Enlightenment (with composite enabled) does the same lagging - so it is not related with unity.
