Diagonal UV lines will have bleed from adjacent pixels and so need padding. Though fixing that alone won’t give perfect results.
If that’s the result of a smart unwrap then the faces are likely not connected to their neighbors so you should do a merge by distance operation and convert the tris to quads before doing another smart unwrap.
