I also use different colors for the cursor in insert mode
vs normal mode with xubuntu-12.04 (with all updates)
and I have not noticed any flicker. Perhaps you can
try whether installing xfce solves your flicker issue:

1/ sudo apt-get update
2/ sudo apt-get install xubuntu-desktop
3/ Log out.
4/ Select xfce to login

I remember having very slow refresh and flicker
in vim a long time ago, and solved it at the time
by installing the latest Nvidia driver.
