Sometimes (quite often recently) Google Chrome gets stuck on my computer - its not responding at all and when resizing the window there is no repaint.
If I then kill the process (it seems to happen both for TERM and KILL), the Google Chrome windows close and everything seems to work for a some short time (less than a minute) and then I get kicked out of the session.
Looking at the Xorg.0.log.old, I see this:
