Current ScummVM snapshot, English version of the game
When you enter the police station at the beginning of the game, you automatically walk through the room, turn to the left and exit through a doorway. There is noticeable jitter at the end of the animation. I tried looking at the positions set for the sprite, and I couldn't see any jitter there so it may be related to drawing rather than animating, but it's hard to tell.
I've made a recording of what it looks like in DOSBox. If you have a browser that supports it, you can view it at http://www.update.uu.se/~d91tan/ScummVM/BlueForce.webm
WebM video file of jitter
Have uploaded the video file as an attachment as it is small enough...
