screen grab of the vnc connection

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.

What is the most recent kernel version (and, if applicable, relevant package versions) with which the problem did not happen?
