A few weeks ago, a bunch of display driver and compositor developers met once again for the third iteration of the Display Next Hackfest. The tradition was started by Red Hat, followed by Igalia (thanks Melissa), and now AMD (thanks Harry). We met in the AMD offices in Markham, Ontario, Canada; and online, to discuss issues, present things we worked on, figure out future steps on a bunch of topics related to displays, GPUs, and compositors.
