Weirdly enough, enabling "Wire" for the object removes the edges caused by triangulation.

It isn't really a Cycles issue, it's a viewport issue. @Brecht Van Lommel (brecht), do you really have time for this?

I might have time, but @Czarek Kopias (kopias), please don't assign bugs to developers, we do that ourselves.

As far as I know outline drawing was never supported for transparent objects, and is intended to be disabled, see e.g. T25764.
