Unfortunately i always get the ghosting effect. But this is something
we will try to fix later.

I had noticed the same thing, but now i tested it and it is ok, maybe

Thinking more about it, it's ugly to have that half-green video frame
even if it's just one. It's better to keep your or Deepthy solution.
