leg_swap

Legs swapped to digitigrade by the legs preference and back, then a digitigrade leg attached as surgery attaches one: each time the uniform is drawn again for the new legs at once (the leg-swap refresh in try_attach_limb() and in the legs preference), so the bulge, whose shapes follow the legs, never sits on a sprite drawn for the old ones.

Proc Details

check_fresh

After a swap to digitigrade legs: the uniform as drawn is the one a fresh render draws for them, not before.
