Interesting that this bug is still marked as unconfirmed. I can clearly
see it myself on my laptop running Ubuntu 14.04. It's not that clear to
me yet when it directly starts but it might have something to do with
hibernation. When it occurs the CPU load of Xorg and compiz is raising
up to 60% and stays at this level until the application gets closed. In
my case it is mostly Thunderbird.

I have updated to Ubuntu 14.10 now, and will closely watch this problem
over the next couple of days to maybe find a pattern to reproduce.

Title:
  Xorg eats processor cycles while waiting for slow Internet

Bug description:
  Top shows that xorg is using >40% of CPU when there's no reason for it
  to be doing so.

  High CPU usage by xorg seems to be associated with slow/flaky
  Internet, e.g. slow sending of email with Thunderbird or slow loading
  of Launchpad in Firefox over a WiFi connection.  It seems like xorg
  goes mental until it receives notification that the Internet transfer
  has completed successfully.  At least Thunderbird and Firefox are
  involved, wget doesn't cause the same problem.

  I'm using an up-to-date Hardy (64-bit) on a Sony Vaio SZ650 (intel 965
  graphics) and iwlagn / iwl4965 WiFi.
