I tried to submit the required debugging information by running the
command "sudo apport-collect 1509868", but it failed showing the
following output:

  I open Firefox and after some minutes using it, suddenly the screen
  display is "visually damaged" by a lot of very thin horizontal white
  lines. This began to happen after upgrading to Kubuntu 15.10 and
  someone via IRC suggested me this workaround: Go to KDE System
  Settings -> Display configuration -> Compositor -> Tearing prevention
  (vsync) = set to 'never'; I did that and by fortune it worked!

  After this bug is reviewed and solved, I would like to restore the
  Tearing prevention (vsync) setting to "Automatic" again.

  Thanks in advance for attending this.
