I normally peg mortise and tenon joints on panels I build. I sand them flush. On a desk I made a couple years ago from poplar and painted, I noticed the other day that the pegs (quarter-inch) now stand proud of the surface slightly.
Does anyone know why that is? and how to prevent it in the future? It’s not terribly noticeable, but I would like to control it if I can.

You mean that the frame shrunk in thickness slightly after living indoors while the peg did not shrink a corresponding amount along its length -- even though the peg was glued in place?

Thanks for the help

its going to happen. So plan on this occuring by giving the pegs detail. Squared pegs can be raised and given a hip style. Round pegs could be given dome effects. Use contrasting woods etc.
I've had exactly the same problem with pegged tenons, though it's barely noticeable. You can just barely feel it with your fingers. I want to try something different next time. I'll cut 1/4" or 3/8" square holes with my hollow chisel mortiser, then drill on that center with a round bit, peg the joint with a dowel below the surface, and use a square ebony plug with a pyramid bevel left a little proud. Since the joinery is the only real decorative aspect of Mission style furniture, why not dress it up a little? This will have the added benefit of allowing me to stain all the parts before assembly, since I won't have to sand the dowel plugs flush after glueup. The ebony plugs can go in last. I have some beautiful old jet black ebony I can't wait to use.
