<pre>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.</pre>
