Hello same problem here on Dell Latitude E7450 with kernel 3.16.0-33 and with xserver-xorg-video-intel-lts-utopic stack on Ubuntu 14.04.2 LTS.
Mostly black rectangles and missing letters, for example in folder's name on the Desktop. This occurs after some time after having boot and probably when resuming from sleep.
I Will try to provide screenshot next time it happens. To resume to a normal situation, I have to logout & logon, but it doesn't work each time.
