Activating/de-activating Loop (transport) causes droupouts

This happens about 75% of the time, in all projects regardless of how many audio tracks and/or VI’s are up:

  1. Play project with audio and/or VI’s active and playing
  2. Press the Loop button (or associated key command) on the transport bar.
  3. There is often an audio glitch/dropout

This did not happen for me in 8.5, by way of comparison.

Can’t reproduce, at least on Windows and 9.0.10. I can even hold down the C (metronome) button.
