Summary0008688: Ripple edit: Disappearing edits, invisible regions
DescriptionI'm using 6.6.410.

When recording and editing voice recordings I uses Ripple mode for some time.
After a while I've noticed strange behaviour and finally a region that was played back in empty space but draw in another place.
After restarting Ardour the region was visible where I've previously hear it's audio (even though the track was empty on that part of timeline).

The problems persisted even when I switched back to Slide mode.

I yet again have to go back to 6.5, because 6.6 is rendering my work way harder than it needs to be.

does the problem still exist in 6.6-436 was it also present in 6.6?

if so, do you have a recipe how to reproduce it?

Just wanted to mention I've been having this issue too. Using 6.6-410 on Windows 10, I'll upgrade to 436 and see what happens.

How can you reproduce this issue?
Can you provide step by step instructions starting with a new session?

v6.6.456 has not fixed this. I can't determine an exact recipe to reproduce the issue, however, editing region lengths then zooming out has triggered it several times for me.

Here's a video demonstrating the problem:
https://youtu.be/JbosJaO4rKc

For me the problem started after I've used Ripple Edit for a while to cut out parts of regions and slide them around.

After that something has been broken in my session ever since and whenever I open it in Ardour 6.6 - some regions have an offset between where they play sound on the timeline, and where they are drawn on the timeline.
When I load the session again in Ardour 6.5 it's fine.

Let me add: the region shown the video has actually been recorded way after I stopped using Ripple edit, but it's affected by this problem.

Since Ardour 6.6 crashed on exporting this session I'm back to 6.5 and I can confirm that the region is visually located where it is played sound in Ardour 6.6.
So the only thing out of place is visual position of the region in Ardour 6.6.
oh, and the exprot crashing:

An x-run occurred while running as freewheel. That should be impossible. Are you using JACK?
It is only however only an assertion. Optimized builds will ignore this.

I have not been able to reproduce this. Can you send a session where the region position differs when its is loaded in v6.5.0 vs v6.6.489? Thanks.

What happens at 0:25 are you using undo?

Another shot in the dark, could you try if the issue is still present in 6.6.492?

That fixes an potential issue when a 2nd ripple edit is started while Ardour is still busy updating buffers for the prior ripple edit.
This can happen with slow disks or with many regions
