Title:
  Intel DRM GPU hang in Kubuntu 15.04

Status in xf86-video-intel:
  Confirmed
Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Intel driver hangs every time KDE uses one of the special system
  effects. I can reliably reproduce it by pressing "Alt-Tab", for
  example. The only fix is to reboot the computer.

  Kernel version:
  $ uname -a
  Linux darkstar 3.19.0-15-generic #15-Ubuntu SMP Thu Apr 16 23:32:37 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
