Chain seems a bit too loose to me. Starting from the big-big combination, where the chain is tightest (3rd photo), the jockey wheels both rotate clockwise as the derailleur wraps chain. Staying on the largest cog, and shifting to the smallest chainwheel, the upper jockey wheel has now rotated to a position where it's starting to interfere with that sprocket. If I shift to the next-to-largest sprocket, the derailleur moves outward, and the jockey wheel has more clearance at that sprocket. Thus, with a longer chain, that interference just happens sooner, because the jockey wheel cage starts at a more rotated position.
I just rotated the whole derailleur a bit more clockwise, by screwing in the B-screw more (dropping the jockey wheels slightly). I think that has helped.
