Title:
  [GNOME3 Staging PPA] strange shadow rendered where client-side
  decorations are used

Status in xserver-xorg-video-intel package in Ubuntu:

Status in xserver-xorg-video-intel-lts-utopic package in Ubuntu:

Status in xserver-xorg-video-intel-lts-utopic source package in Trusty:

Bug description:
  [Impact]
  The Intel video driver has a bug that can cause to incorrectly draw certain trapezoids. This is visible when using client side decorations in GNOME 3 (see attached screenshots).

  [Test Case]
  Run GNOME 3 with client side decorations on Intel hardware.
  Observed result:
  Shadow under window is missing corners.
  Expected result:
  Shadow looks correct.

  [Regression potential]
  Low. The fix is from upstream and just changes the logic error in the CompositeTrapezoids routine.
