There are several aspects to the fix: - Always calculate bounding box for meshes and curves from dependency graph evaluation function. There is a reason why mesh was tagged for geometry update, so can not be spare here in attempts to avoid calculation. - Remove texture space evaluation from RNA accessor. Such data is to be evaluated by a dependency graph. Don't see a reason to be different here: we never force evaluation of any kind from RNA. - Copy bounding box and texture space to original object for active dependency graph. This matches object-level bounding box and allows to remove bounding box evaluation from RNA.
