Comment 9 for bug 1218735

This bug was fixed in the package xserver-xorg-video-intel - 2:2.21.14-4ubuntu4

---------------
xserver-xorg-video-intel (2:2.21.14-4ubuntu4) saucy; urgency=low

  * XMir: Make a conservative guess as to whether the Mir buffer will be used
    for scanout, and take caching decisions appropriately. Fixes "cache dirt"
    transient horizontal-line misrendering with Mir bypass (LP: #1218735)
  * xmir.patch: Split monolithic concatenated patch out into a quilt patch
    series.
