Hi,

the same problem hit me with Debian Stretch on a Thinkpad X201s. 

As a workaround I currently use the intel driver:


/etc/X11/xorg.conf.d/20-intel.conf

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


Another option might be disabling or deinstalling "tlp", but I#m not sure yet.

cu,
