Performer with funny traits (6)
I believe the answer is:
artist
'performer' is the definition.
(eg a musician)
'funny traits' is the wordplay.
'funny' indicates an anagram.
'traits' with letters rearranged gives 'ARTIST'.
'with' is the link.
(Other definitions for artist that I've seen before include "Constable, perhaps" , "eg Monet" , "Creator of aesthetic works" , "Skilled person" , "Bacon, for example?" .)
