Realized chord symbols are not swung.
If you have a chord symbol placed on an offbeat 8th note on a swung piece, the chord symbol will be played as if it straight. This is mainly apparent when you have a notated line, which plays swung, as well as the chord symbol. It results in this jerky effect where the chord is played really quickly before the notated notes. This can be made more apparent by setting the tempo to very slow, alloying you to individually hear the chord being played slightly earlier than the 8th note. I've included a picture of the score at this moment as well as the score itself. Not a huge annoyance, mainly posting so the team is aware of it.
