(Guitar Pro 8 / Version 8.1.5 / Build 31)

At first I thought I had entered something wrong. But the eight chords show that in the first part of the video, every 2nd chord sounds different when strummed. In the second attempt, I set the strum direction to "down" for all chords. In the third part, I additionally added a downward arpeggio to each chord.

For chords 1, 3, 5, and 7, the string strikes on the D, G, and B strings are played with an offset. For chords 2, 4, 6, and 8, this offset is noticeably smaller/shorter, even though the chords were duplicated via copy/paste.
