The paint I was using wasn't shaken, but when I stirred it up I made a few bubbles which went away pretty quick, I dont think any of them stayed on once i started rolling.

When I roll, I make a few bubbles though and they seem to go away on their own, then when I very lightly roll over the area a minute or 2 after first applying, it evens out the extra tiny glob of paint left by the bubble. The thinner you get the mixture, the quicker the bubbles go away in my experience.
