I am an experienced contractor and painter and have come across this dilemma more than once in my life time.
Recently I did a renovation with about 60 boards of drywall. After taping and sanding I primed it with Zinsser 123 primer. After priming I lightly sanded the walls with a very fine paper before applying the first coat of paint…not a big deal. I applied 3 coats of Benjamin Moore Moore Craft white to the ceiling and all the areas which have compound are showing different than the areas that don’t have compound. Same problem with the walls that are painted with a tan color. It looks awful. I used flat paint for everything and the all the areas that have joint compound show up a different texture…almost like a sheen is bleeding through.
I can only assume it is the primer. Are there more preferable primers to use under flat paints? What primers do not dry with a sheen? Thank you in advance!

I have experienced and seen this before. 123 is a good primer but the problem is the difference between the paper face of the rock and the compound, they have different textures and they absorb the primer differently.
One way to stop this is to use USG First Coat, back rolled with a 1/2 inch lamb skin roller, before applying the paint. The First Coat minimizes surface texture variations and back rolling adds a fine even texture that helps even further.
