Hello,

The bug has been debated here
https://trac.videolan.org/vlc/ticket/12622

And here seems to be found a possible patch, not yet applied

https://trac.videolan.org/vlc/attachment/ticket/12622/vlc-2.2-greenline.patch

That patch is incomplete and I suspect it will lead to crashes in some cases.

I still consider this a bug in XVideo drivers, but there is a work-around in VLC now. Unfortunately, that means XVideo output will require memory copying. This is not avoidable without a fix for the XVideo drivers (which is unlikely to happen anytime soon).

Probably this bug happen only with libav and not with ffmpeg

So that sentence sounds a lot like trolling libav developers and the choice of libav by the Debian multimedia team. I don't know where you stand on libav vs ffmpeg, but the green line issue is solely between VLC and the XVideo drivers. VLC and at least some XVideo drivers disagree on how scaling cropped pictures should be achieved.
