Title:
  xorg freezes mouse and consumes cpu especially when more apps in
  memory

Status in “xorg” package in Ubuntu:
  New

Bug description:
  Freshly built Lubuntu Desktop amd64 14.10 beta 1 (20140826.1)
  Hardware spec from hardinfo - https://gist.github.com/74e638f3a308f6aaef53

  When using more memory on system (e.g. multiple apps or many browser
  tabs) the system will freeze for 10 seconds to over a minute, with the
  mouse cursor not moving at all, and no screen updates. When it finally
  responds I see cpu spikes in xorg process with lxtask showing over
  100%! Shutting down applications or tabs to reduce memory load seems
  to make the issue go away, but trying to multitask renders system
  practically unusable.
