Initialization stops before the GNOME login screen and shows 2 errors. The first one is the one causing the initialization to hang, and the 2nd goes away if I disconnect my second monitor (I’m on a Haswell laptop, btw).

When opening GNOME Activities, sometimes, some window previews don’t show at all inside the workspaces, despite the positioning of the window previes inside it hinting at a invisible window being there.
Here’s an example. There are actually 2 windows open, but only a single one is shown, despite the arrangement taking into account the existence of another window there.
