Public bug reported:
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.
