Since GStreamer 1.0 we sometimes allocate a larger XV image for the video with
padding on all four sides but then call Xv(Shm)PutImage() to render a part of
this image. With intel drivers this (depending on resolutions) sometimes causes
a 1-2 pixel wide green line at the right side or bottom.
The resolutions in question or usually perfect multiples of 16, e.g. 672x416 is
allocated and 640x360 (16 pixel padding at left/right/top, 40 pixel padding at
bottom) is rendered.
When allocating and rendering 672x416 or 640x360 directly (i.e. no offsets or
anything) there are no green lines anywhere.</pre>
