Title:
  [Ubuntu 15.10] Intel Display i915 driver crashes, Asus Zenbook 303LA

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Wily:
  In Progress

Bug description:
  My Asus Zenbook 303LA (UX303LA-DS51T) eventually gets a corrupted
  display. Everything repeatedly shifts horizontally. I found the
  following in the kernel log. The corruption does not have a 1:1
  relation with the occurrence of the error however.
