No sorry bisections are not appropriate yet. As the latest
mainline after all still has the bug I am trying this work
around as per Phil Hopkins:
Older Intel graphics adapters may need UXA acceleration instead of the
default. The work-around is to change the Xorg acceleration method to
UXA.
Edit (or create) as root or sudo a file named /etc/X11/xorg.conf as
follows (there should be a tab before each line except the first and the
last):
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
So far on the stock 15.10 4.2 kernel no problems. Will give it
a few more minutes.

Title:
Kubuntu Wily upgrade screen glitch with 4.2 kernel
Status in linux package in Ubuntu:
Incomplete
Bug description:
On recent update from 15.04 to 15.10, the new 4.2 kernel is
associated with graphics instability after a few seconds of GUI use
with mouse and keyboard making the GUI unusable. See another
person's same experience with intel graphics here:
askubuntu.com/questions/688649/kubuntu-wily-upgrade-screen-glitch
Downgrading to the last 15.04 kernel solves my issue.
See result of ubuntu-bug linux from the terminal attached.
