Comment 3 for bug 480955

@ ~suv, that's probably because you've enabled snapping of nodes, and not snapping of bounding boxes. When snapping nodes, Inkscape will always use the geometrical bbox because nodes are always in the middle of a stroke. In all other cases Inkscape will follow the preference set for the bbox, i.e. visual or geometric.

@ loke: The behavior you described in the first comment might be awkward, but at least it is consistent. If this is to be changed, then Inkscape should discard the filters when calculating the visual bounding box for transformations. In other cases, e.g. when exporting, the filters should still be included in the visual bounding box. The real bug here could be that the bbox is much too large. If it would tightly fit around the object and its applied filter then this behavior would not be as annoying I believe.
