When the room gets warm, a small crack appears at the joint between the flat ceiling and the the ceiling pieces that slope to the walls. It disappears when the room cools off. I've tried joint compound and it looks great until it gets warm again. Then I have a crack which goes away when it gets cool. I cannot use paper or fiberglass joint tape because of the swirl pattern on the ceiling.
Interior 10' swirled mansard ceiling. Reappearing cracks due to temperature changes.

Caulk them instead. Latex Caulk will hold paint beautifully and move with the seam's mood. You may have to caulk up to 3-times to get it perfectly flat and flush with the drywall, but it should last a good long time.
