My first issue with CP - probably the most well-written/designed piece of FS add-on I've ever tried, well done to Kevin and all the team.
In external views with the aircraft on the ground I'm getting a shaking of all scenery - terminal buildings, airbridges, ground etc. This stops when I turn the engines off. I've tried turning down all the turbulence settings for a particular external view (aircraft), but the shaking remains. Mildly irritating but also increases shimmering of textures.
