--- Comment #8 from Chris Wilson <chris at chris-wilson.co.uk> ---
Ok, a couple of quick(er) tests to try then:

echo > /etc/X11/xorg.conf.d/20-intel.conf <<EOF
Section "Device"
  Identifier "igfx"
  Driver "intel"
  Option "AccelMethod" "blt"
  #Option "AccelMethod" "none"
  #Option "AccelMethod" "uxa"
EndSection
EOF

then switch between blt/none/uxa for a couple of test runs. Other tests would
be running at different modes, or even enabling Option "TearFree" in the above
conf snippet.
