Xorg.log
CPU: Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz
OS: Ubuntu 14.04
kernel: 4.2.0-rc8+
mesa: git master (c8a61ea4fbcb)
libdrm: git 56d8dd6a9c0
xf86-video-intel: git master (300319e2044c)
other components should be stock Ubuntu 14.04 (desktop environment: Xfce 4.10)
When playing The Talos Principle in windowed mode, there is severe
flickering/stuttering. I've noticed that xf86-video-intel from stock Ubuntu
14.04 has no such problem, so ran bisect which resulted in:
commit 72d208a7f2f0e8f2d93483e535154f34a8a26d81
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>

sna/dri2: Perform swap elision on windows for swap-interval==0
The commit doesn't revert, but checking out, building and installing
72d208a7f2^ gives properly working game after restarting Xorg.</pre>
