I have brought this up before. I thought it might be the lower intensity boil that the low-O2 suggests and neddles had some similar issues that he thought might be from BTB. On one of the last batches I made I intentionally made sure that the boil intensity was more vigorous. I also added a gel solution to that keg assuming that the beer would finally be clear. It's on tap now and it's cloudy. There are two constants: One is that the beer will pour into the glass and you may see what looks like clear beer and then you see a very distinct "cloudy part" of the pour that is visually different from the rest of the pour... almost as if the yeast on the bottom of the keg is not settled or like it's fluffy and cloudy at the bottom. The other is that the beer is decently clear as the end of the keg is near. Maybe the last gallon or so will be somewhat clearer. This does not seem to be chill haze as the beer remains cloudy when the beer is warmer. You can see a visual layer of yeast at the bottom of the glass when you're done. WTF is going on here?
This has happened now with multiple batches with 1056, 2124 and 2278. Some of these beers have been more clear than others but nothing reaching what I used to be able to do.
