Nope.  Same  graphics problem  exists for   me with 4.2.5-wily  kernel
[sans xorg.conf].  Any  good   kernel is  likely  to be  an  earlier one,
not  a  later one, as  the  regression is  yet unidentified.

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.
