Now I'm just trying to figure out why it's ignoring the NSBackgroundColorAttributeName attribute.
Well I think the problem is that NSBackgroundColorAttributeName is a higher level thing. In the Cocoa text system, the NSLayoutManager is responsible for drawing it, and that's done with separate methods, in the same way as rendering the selection highlight.
While I haven't used Core Text myself, I imagine it's architected in a similar manner, so CTDrawLine() is very unlikely to render anything other than the glyphs. CTFrame *may* be able to render the background, so if you need that functionality and don't want to draw it yourself you could try creating a CTFramesetter rather than a CTLine and using that to generate a CTFrame that you then draw. Otherwise I think you'll just have to draw the background manually.
For the time being, I've got a workaround in just drawing the background color with NSRectFill, but this feels like a kludge, and that I really should be doing something differently to draw the background the "right" way.
I guess my only comment there is that it might be more consistent to use CGContextFillRect(). Not that it really matters either way :-)
