Oded Arbel, closing as per

given this is no longer reproducible.

** Description changed:

  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:
