Fix Ubuntu 17.04 graphics flickering and compiz regularly crashing
[preisrechner]
On a machine with Intel on-board graphics (i915 driver/ OpenGL MESA) and a fresh install of Ubuntu 17.04 I've seen strange flickering on application chrome and whenever something from Unity triggered an animation (over overlays - I'm not sure), like the Dash being opened, the docker appearing, etc. - then Compiz crashed. This is either Unity (probably) or compiz having a bug (this one?)
From the comments on this bug report, a quick fix was to disable Unity altogether via ccsm (compiz configuration manager) and replace missing UI components like the app launcher, app dock, task bar / clock with another app for that - like cairo-dock.
Comments about where this erratic Ubuntu Unity behavior is coming from are welcome!
