screen grab of this bug over vnc

Details:
Upon connecting over vnc to an Xorg server (in this case running Kodi), the resulting video flickers and tears quite severely.  An example screen grab of a vnc session attached to illustrate what I am seeing is attached.  In the past such connections have been very smooth and pleasant.  I see nothing diagnostic in the output of dmesg nor in the output from my vncserver.  I can confirm the behavior with both the x11vnc package and the x0vncserver supplied with tigervnvc.

Glad to supply any diagnostic logs upon request.

Distro:
Arch Linux x86_64

Hardware:
Intel(R) Core(TM) i3-4130T with on board video.
Motherboard: MSI H97I AC (latest BIOS)

Video drivers and xorg version:
kernel version 4.4.5 and 4.3.6 both give this bug
xf86-video-intel 1:2.99.917+560+gd167280-1
libva-intel-driver 1.6.2-1
xorg-server 1.18.1-3
Comment 1 John 2016-03-30 07:30:28 UTC

leave closed - fixed for me on ubuntu 16.04 + HWE stack (kodi 17.1 + x11vnc also)
