+ ====Original Report====

  [Impact]
  Windows don't move when dragged with the mouse, except intermittently. Very poor user experience.
  
  [Development Fix]
  Deleted a temporary workaround for an old bug in the move plugin, which itself was buggy. It was causing the move plugin to unexpectedly revert from the default "lazy" asynchronous mode (fast) to a blocking synchronous mode, which is simply too slow to keep up with the mouse on some machines.
  
  [Stable Fix]
  As above.
  
  [Test Case]
  Drag windows around rapidly using the mouse.
  Broken Behaviour: Windows don't move, except maybe once every 1-2 seconds.
  Fixed Behaviour: Windows move smoothly and keep up with the mouse.
  If you can't reproduce the bug then try using a very slow or old machine. I used an N270 based Atom netbook.
  
  [Regression Potential]
  Low. The fix has been in every-day use by many users of ppa:vanvugt/compiz for a while.
  
  [Original Report]
  I have fast machine( 4gb of ram, amd64 x4, nvidia 460 ), using proprietary nvidia driver.
  Natty b2 x64, updated yesterday.
  
  Windows move very slow, but only by mouse. Windows moving fast by Put plugin.
  lasy_positioning is enabled.
  
  Disabling wobbly windows and switching window decorator not helping.
  video:

  When video is recording, windows moves much faster. Maybe problem with screen redraw.
  If you need, i can record video by camera, windows moving unreal slow when video not recording.
