See the attached images: the correct one is with Project properties > OWS server > WFS server precision 8, the wrong one is with precision 0.
All rest equal.

Hi Paolo,
I don't have either a working WFS right now. That would be neat to use make the OGC testing instances permanent and well advertised. I'll ask Paul about this.
About the precision issue, isn't it that your data is in WGS84 and that asking for a precision of 0 leads to severely truncated geometries ? If right, this is not an issue I think

Project in 3857, data in 3003.
Thanks.
