Comment # 2 on bug 1014831 from Michael Lashkevich

As a workaround I used an advice found somewhere on the Internet and added the
following lines into the file /etc/X11/xorg.conf.d/50-device.conf:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"
   Option      "AccelMethod"  "uxa"
EndSection

Since then I have not experience such freezes.
