I was quite convinced the problem must be with 10.9 and the graphics card on this model of MBP, from Rob's post and the many reports I've now seen on Apple's discussion boards about graphics problems on these machines under Mavericks. But... after this morning's update to 2.0-alpha.9495 the graphics switching is no longer occurring. So far.
There's nothing about this in the release notes, but if you fixed something, thank you. Otherwise, it's a bit of a mystery. Perhaps some cached information expired somewhere.
