did you wipe the dust off after you sanded?
I had the same thing happen to me on a customers house I was painting, except the walls were years old, he's correct I bet if you pop a bubble it will be full of dust, the only way I found to eliminate the problem is to either use nothing but oil based products on the surface which I wouldn't recomend or use fans to dry the paint as fast as you can giving the paint no time to penetrate the previous coat.
What I did was scraped off the bubbles with a mud knife and lightly sanded with a sanding pole, then prime with an oil based Kilz, you may still see a few bubbles but not many, this will prevent your top coat from being able to penetrate the surface as fast, then proceed in painting and as soon as your finished use a couple round metal fans on full.
Behr paint is noted for being lumpy (gritty) but that almost looks like something in the paint. Did it bubble with the primer also or just the paint? Did it bubble in the same place on the second coat as it did on the first? And as the others suggested it could be drywall dust. After sanding the area it needs a good cleaning and wipe down with a damp rag, the entire ceiling not just where you patched.
I've had similar problems with joint compound when I thinned it too much with water. I use Synko ProSet 90 Lite Sand which doesn't have much glue in it. To get a smoother coat, I would use a spray bottle to mist the joint compound with water and trowel it when it was wet. I found that doing that would give me bubbles, and I attribute that to the moisture absorbed into the joint compound wanting to evaporate. I'm thinking that because I troweled the joint compound wet, I diluted what little glue was in the joint compound, and the powder at the surface didn't have enough glue in it to hold it together. So, when the water in the primer wanted to evaporate from the joint compound, it pushed the primer off the powder to form a bubble because there wasn't enough glue in the powder to hold it together to prevent that from happening.
I'd say your best bet would be to use your joint compound to fix those bubbled areas, but don't thin your joint compound with too much water. I attribute that excessive thinning with water to be the reason I got bubbles in my latex primer.
You pour the paint into the paint tray liner and then "roll" the paint up the ramp of the paint tray liner with the roller until the entire outside of the roller sleeve has paint on it.
You and I must be the only ones left.The pan vs bucket debate is an old one. My father who trained me didn't like pans, partially because of the reason stated in the video that it's easy to step in a pan if your not paying close attention.
I've switched mostly to pans lately. They seem to load the roller a little better but either way can work fine.
