vray toon and opacity bug

[colorbleed]

Hi there,
I have a very strange issue. I’ve scattered some planes onto a surface and apply a toon shader to the surface and the scattered planes. The planes receive a simple texture input in the opacity channel. In IPR all works fine, but bucket rendering gives weird artifacts around the transparent edges, shown here. PS: I drew in the green squiggly lines;))

Now, as soon as I add ANY render element, no matter which one. The artifacts disappear and everything looks correct. As seen here:
