While talking to the Jarl and steward of Markarth, I happened to turn around just to see what it looks like from that vantage point in Understone Keep. Answer: quite a long look down the corridor that leads up to the throne. Kind of a forbidding and depressing view, really.

Came out of Lakeview Manor and saw a bunch of background stuff behind the nearest trees just completely failing to render, mostly sky, but a few other elements as well. And you can see a partially rendered tree on the left edge of this screencap.

Another angle on the same graphical breakage, though here everything in the foreground looks more or less normal. I kind of like this effect, actually, it makes it look like there's a thunderstorm rolling into the area.
