I also experience this problem. I've been having it for a while. Logging out and logging in again temporarily fixes the issue. Affects both KDE and Gnome. Got this in /var/log/syslog when the problem happened just now:

Let me know if you want more information. This issue bugs me a lot. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/996008 Title: GUI slows down significantly after random period of time. Status in “compiz” package in Ubuntu: Confirmed Bug description: Like a number of other users, I'm getting some variant of graphical slowdown after using my desktop PC for a random amount of time - between minutes and hours. I suspect the problem lies with compiz, OpenGL or graphics card drivers (NVidia in my case) as I have seen this behaviour with both Linux Mint 11 and 12 in the past, on the same PC. I don't believe there to be a hardware problem as this machine works perfectly fine running high-end games under Windows. Restarting or logging out and in often temporarily resolves the issue... but it eventually returns.
