We were facing some problems with Ubuntu 16.10, i think that the problem is related to Unity since i was having some crashes pointing to the hud-service.

I tried on different platforms facing same behavior but showing different messages.

Fresh installation, Ubuntu 16.10, upgraded.
Flickering: xscreensaver 1920x1080.
Games: open arena and extremetuxracer crashes

We are pointing to Unity since 16.10 introduces some changes.

Configuration (example):

The way to reproduce this behavior is simple:

1. Login with your user and password.
2. Execute xscreensaver, openarena or extremetuxracer

All of these programs should run smoothly without flickering or issues. 

Actual behavior: xscreensaver shows a lot of flickering not matter if we try with other resolutions or frequency.

Mentioned game just crash , open arena shows segmentation fault and extreme tuxracer only goes over last video layer not showing actual game.

This component is (was) for tracking the release process itself; this bug is not about that.
