Seems this is a docky issue. With docky open you get a massive black box on the screen. Closing docky causes it to go away.

[Rico Tzschichholz (ricotz)]

Docky needs a window manager with enabled compositing support. There are plans to support non-compositing with less features enabled.

Actually I already pushed some basic support for non-composited screens.
