Bug#765969: [vlc] green line under some Mpeg-4 XVID videos

[Francesco Muzio]

The green line is visible also is visible also when the height of the 
screen matches the height of the video. Hence the line is overlapped the 
bottom of the screen, but don't change its colour o brightness during 
the playing. (if I understand correctly your question)

The attached screenshot has been taken when VLC is playing the video 
linked in my previous message.
I have tried the default output module "VDPAU", the OpenGL (XCB) and the 
X11 (XCB). same result for all three.
I have also restored the options of VLC without sucessful.
