Donkey shifted a bit going round small carbuncle (7)
I believe the answer is:
eyesore
'carbuncle' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for eyesore that I've seen before include "It's offensively ugly" , "offensive to viewers" , "Something exceedingly ugly" , "Blemish" , "Thing that is ugly to look at" .)
