Hello,
I tried using opticalflow and vectorblur to add motionblur to a footage, and I noticed a line artifact at the bottom of the image.

After asking around it seems it's being caused by the gpu. There's also a forum thread about this problem here:

I tried rendering while the sequence was being cached and it resolved to a crash, I made a bugreport about it too.
