Also experiencing this issue on a W530 running Fedora 18 with 3.11.10.
My second monitor is connected via the Lenovo dock connector. The bug
does not appear if the display adapter is switched to Discrete mode in
BIOS. I have also experienced this bug on a projector connected via VGA.

Title:
  [prime] unsynchronised rendering on secondary displays

Status in Accelerated Xorg driver for nVidia cards:
  Confirmed
Status in “xserver-xorg-video-intel” package in Ubuntu:
  Confirmed

Bug description:
  Symptoms are the same as in bug 
  https://bugs.launchpad.net/ubuntu/+source/unity-system-compositor/+bug/1221399
  For example, see attached photo, replicable 100% just by moving the mouse 
fast.

  In bug https://bugs.launchpad.net/xmir/+bug/1218735 I was told to fill
  a new bug.

  Note that this Thinkpad has two video cards. I don't know how to tell
  if Intel or Nvidia is being used. I'm using the default saucy install,
  no additional drivers.
