Comment (by hamakei):

 Confirm it's still there in the latest (July 17th) build.

 When waving the mouse around "empty" there is a very, very slight
 delay...almost unnoticeable. If you throw the mouse around very quickly,
 then as dafioram mentioned, you can end up in a situation where the
 pointer image doesn't match what it should be based on it's location on-
 screen.

 If you pick up and drag an object, then the delay is obvious....like some
 weird version of mouse acceleration where everything is a second or two
 behind.

 But the parrot....that adds 15-20 seconds to my movements. Which is what
 makes me wonder if it has something to do with the animation complexity...

 Btw...I'm running on a quad-core 3.9.Ghz system with a dedicated nVidia
 GPU unlike dafioram...I ran "top" alongside the game and noticed something
 similar. When playing normally, the scummvm process was using between 5
 and 12% of my CPU. If I picked up the Liftbot's head and started waving it
 around the screen, it immediately jumped to 30-35%.

 I *did* notice that during the elevator animation the CPU usage jumped to
 50%, which does suggest there is something weird going on with the
 animation playback in the game...this could all be related...but it
 shouldn't take so much CPU power just to play a non-interactive video...

 When I picked up the parrot it jumped to a ridiculous 75% CPU usage...
