3) Graphics-wise, it's a standard installation except for the 4.9-rc3 kernel from mainline and a PPA for nvidia graphics drivers (but I wasn't using the nvidia card at the time this happened, it was all on the Intel GPU).
I only mentioned it because it looked exactly like what this bug would have looked like if the laptop screen had been resized to a larger vertical resolution, say from 1920x900 to 1920x1080, and because just like this bug, killing and restarting nautilus fixed it (and I *was* already running the updated nautilus 1:3.20.3-1ubuntu3.1).
I haven't seen it happen again, though, so it's not worth following up on at this stage since I can't readily reproduce it.
@Christopher:
1) It's a physical machine (my laptop).
2) I'm using Ubuntu 16.10.
