Unity compiz and Xorg processes are not growing, this seems like a KDE + Nvidia + Xorg issue.
I tested firefox without hardware acceleration, but still growing kwin and xorg processes.
You can easily reproduce this, when you start in KDE the system monitor krunner (Ctrl+Esc), then search for kwin.
Do not start other applications and watch the process memory growing.
Thank you for the nvidia-link, I'll report it, when I have more time.
