So exactly what is wrong:

It seems to be nvidia's proprietary driver problem on 8*** cards when
using external monitor with large resolution (1920*1200). Compiz is very
slow to handle opened windows.  Works fine without the external monitor
just at native notebook's resolution.

The only solution is nouveau driver. Appears to be working fine  at
acceptable performance except of the time when Unity crashes itself.

So as I understand ubuntu's team won't be able to help with this issue?
