skylake video

[Andrew Slaughter]

Using compton with backend "glx" and vsync "opengl-swc" ("sna" acceleration
and "tearfree" enabled in the driver) reduced the tearing significantly for
me (on both XFCE and spectrwm), although it didn't eliminate it (mainly
left with some minor corruption of fonts in firefox). It seemed usable,
though.
