Artwork Causes Glitch in Track

If you add artwork to a track in Rekordbox 6 (I have not tried with other versions) while that track is open in the player, it will cause glitches in the track that persist as long as the track is in the player (i.e., you can scroll back and replay and it will still be there). However, when you eject and re-load the track, the glitch is gone.
