Public bug reported:
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

Note that this still happens on trusty with all updates installed as of
few minutes back.
