Comment 5 for bug 71364

I didn't have a drirc. After creating one and setting vblank_mode to 0, the
problem remains.

$ cat .drirc
<driconf>
    <device screen="0" driver="i915">
        <application name="Default">
            <option name="force_s3tc_enable" value="false" />
            <option name="fthrottle_mode" value="2" />
            <option name="vblank_mode" value="0" />
            <option name="allow_large_textures" value="1" />
        </application>
    </device>
</driconf>
