This maybe intended behavior but when I increase the Preferences > Advanced >Playback > exclusive output modes > hardware buffer in milliseconds to a large value e.g. 1000 and play a song the seekbar wiggles backwards and them jumps forward. It doesn't impact the playback when the seekbar is moving around. I was just playing around to try and fix my occasional glitching with playback.
Here is a link to a GIF showing the issue.
