Testing 4.6 DRM/i915 from cftdisk_2016053119.img on rMBP 13=E2=80=9D =
Late 2013. This is a Core i5 Haswell 4288U with Intel Iris 5100.=20

In principle built-in Retina screen, HDMI and mDP are working =
simultaneously. FPS of 3D accelerated demos such as Teapot fluctuate =
wildly and exhibit significant stutter. Might the issue be temperature =
throttling related?

Unfortunately the disk image from 31-May-2016 20:18 does not include =
XFCE or KDE4. Joeuser=E2=80=99s xinit refers to a file that does not =
exist.

I will set up a more complete testing environment as time permits and =
investigate the performance issue further.

Many thanks to mmacy and everyone else for their contributions towards =
the updated graphics stack on FreeBSD.=
