Comment 48 for bug 1293384

Here is my two cents:

I had the same problem. I did what #15 ( https://bugs.launchpad.net/compiz/+bug/1293384/comments/15 ) suggested and, so far, I only have a spike periodically (primarily when I do anything with the windows and when I switch workspaces).

I did not do the part about editing the /usr/share/gnome-session/sessions/ubuntu.session file as that change removed my action bar (the bar on the left side with the ubuntu icon).

I think this might be a step in the correct direction, in terms of a work around.
