Since it just came up again.
Agreed.
I'm sure it's got issues but their various set ups are exacerbating some of them. Given that they are still leaving green screens behind themselves (during the calibration for that previous game we saw a big green screen behind Jeff who's having the worst tracking problems of the two) I wouldn't be surprised if even at home they are making some questionable decisions about what light sources are in view of their camera. Especially since a few adjustments they've made have clearly somewhat helped their tracking, like finally moving the couch closer as Brad mentioned earlier.
