Public bug reported: After starting to use Oneiric, I have noticed that the window manager system "freezes" from time to time when switching workspaces or when opening the workspace switcher. The window almost switches to the other workspace, before the whole screen freezes. I can't exactly replicate the exact time when this happens. It has also happened when opening the workspace switcher, and (I think) when using the "circle application switcher" from the Compiz plugin. I can still move the mouse and hear sound from the speakers, but I can't interact with anything on screen. I can still access the "tty terminals" with ctrl+alt+F2 (for example), and kill the X process (/usr/run/X :0 ... a relatively long string with "auth", "something/lightdm/something" and so on) to go back to the login screen.
It looks like the animation or drawing of the windows stops too early, and the desktop is then noninteractive. It might happen more frequently when the system has a high CPU load. I did not notice these problems when using Natty and Gnome2.
