Bug detailed description:
-----------------------------
It fails on HSW+ platforms. It's Xf86_video_intel regression.

glx_glx-swap-event_interval and glx_GLX_MESA_query_renderer_coverage also fail
on HSW+ platforms with same bisect commit.

Following cases also fail on BDW and BSW with same bisect commit:
spec_OpenGL_1.1_read-front_clear-front-first_samples=2
spec_OpenGL_1.1_read-front_clear-front-first_samples=4
spec_OpenGL_1.1_read-front_clear-front-first_samples=6
spec_OpenGL_1.1_read-front_clear-front-first_samples=8

Bisect shows: b6eeb7a1f7efa591504070b606be655e27e6e9c2 is the first bad commit

    Disable DRI3 by default

    The external libraries, both in git, and especially shipping already
    enabled in distributions, are buggy and lead to server crashes and
    lockups. Caveat emptor.
