Vertex compression - position snaps vertices

Hello, I am experiencing weird bug with Vertex Compression while compressing positions. For SOME of the instances of SOME of my models in a scene, it visualy snaps the model vertices onto some grid (or rounds the values ?) when builded as AssetBundle - please see images below.

Scene is approx 200m^2. Models is ok in editor, import settings are same for all models in the project.

Any ideas? I am using default pipeline, Static batching a standard shaders. When I disable position compression, it will not mess up my models.

It seem like it is connected with Static Batching, when disabled, it works good, but that is not an option due to optimizations.
