Quote - i exported the toonID pass. auxiliary render

why are teh edges so bad? why are they not mooth? 

render settings were ok. every pass has good edges. only the toonID has this.

pixel samples : 3
shading rate : 1

i have now the service pack 1 instaled.

and it looks like that the auxiliary passes still render without smooth edges. like pixel samples was 1.

the strange part is that the main render has good edges.am i doing something wrong or is this a bug?
