Summary0010177: Ardour9 region gain changes provoke temporary playback shift
DescriptionArdour9 region gain changes provoke temporary playback shift of the tracks having those regions. I will describe variants below.

I can systematically reproduce the following issue in Ardour9. It did not exist in previous versions.
Steps To ReproduceCreate a new session or use an existing one. Make sure you have a least some tracks with each one or more regions.

If boosting or cutting gain one or more regions simultaneously (perhaps also with other region operations) Ardour is somehow processing this request, causing the track(s) of some regions to be temporarily moved in playback. These are the two variants that I already found:

1) If playback was already ongoing, it suffices to boost one region, resulting in the whole track being shifted in time in the playback.

2) If playback was not yet ongoing during region edits, I can only reproduce when selecting multiple regions on different tracks and then boosting these in one go. Then immediately play the transport. It seems like Ardour9 has already processed some region gain changes and the tracks containing these are correctly played in the time domain. However maybe the tracks containing regions that did not receive the finalized gain boost yet, are still shifting in time in playback.

If stopping the playback and giving Ardour9 the time to finalize the processing, the playback is once again correctly. It's not a permanent issue in the session.

However during bulk edits this slows down the whole editing process, which is annoying.
