System Information
Win10 home 64bit (10.0.14393)
i7 7700K
GTX 1070 (Dirver: 378.66)
32GB RAM

Blender Version
Blender 2.78b 3c04373(2017-02-08)
Short description of error
I made a scripted scroll-demo, as you can see in my attachments the area of cubes is surrounded by a icosphere with hair inside. I used this for the stars in background.
Actually I rendered 1738 images overnight and there are artifacts (see magnification) - when I make the icosphere invisible the artifacts disappeared.

Exact steps for others to reproduce the error
.blend's size is 2.2GB because of scripted frames - how to tansport this file to you?
Update:
I packed the .blend and attached it. It has over 7k scripted frames inside but if you want to start it clear you'll need the bitmap.py inside the archive and change the path in the "main" script.

Has this functionality worked for you in the past on older versions of Blender?
If so, which versions?

Hi Joey,

I didn't try older versions of Blender yet - but I figured out, that the artifacts disappear when I switch off the childs in the hair-tab.

In older versions of Blender I did many things with hair, I replayed many yt-tutorials and never had such effects.
