As clarified by Even Roault, this is due to the fact that the ""old"" extent is still stored and the new extent will be the minimal bounding box of ""old"" and ""new"" extents. Of course it can be costly to recalculate the extent of the entire layer on every modification, but perhaps there could be an explicit method to force this? (Which Qgis-devs could then call on edited layers, since extents of manually edited layers in Qgis also come out wrong.) " enhancement closed normal 1.9.0 OGR_SF unspecified normal fixed
