** Description changed:

  Binary package hint: nvidia-glx-180
  
  Hello! I'm running up-to-date Jaunty on a machine with an nVidia 9600GT
  card. It uses the nvidia-glx-180 binary driver. My screen is an HP
  LP2475w.
  
  Things mostly work great, except for a tiny annoying issue: On some
  movies I get visible streaking in the upper part of the screen. I looks
  as if the frames aren't flipped when they should be, on vblank.
  
  (I've got __GL_SYNC_TO_VBLANK is always set, enabled it in nvidia-
  settings, and in Compiz.) This isn't a performance problem, for instance
  it happens repeatedly with some low-resolution movies, but never on some
  HD movies.
  
  It's mostly visible when there's some horizontal panning, and I'm not
  sure if it happens all the time and it's just less noticeable then.
  
  This happens with both XVideo and VDPAU outputs, in all video players
  I've tried. Also, both in full-screen and windowed mode.
  
  I'm attaching a screenshot; it's not exactly what I see on the screen,
  but it gives a good idea of what it looks like. (Warning, it's a pretty
  big file.) What I see looks exactly like the part marked “A” in the
  picture, and in the same spot, as far as I can tell visually. However, I
  never noticed streaking in the parts marked “B”, so I assume those are
  caused by the screenshot. (I suppose that's another bug in itself.)
  
  Any idea how I might diagnose this further?
