Ardour very unstable on newest version (0.3.29)

Ardour crashes and freezes often lately. This already happens since at least a week on master (#1103 (comment 935990)) and now landed in 0.3.29.

How to reproduce:

  1. Start Ardour while using pipewire-jack / pw-jack and load a session. This already doesn't work sometimes. It just stays at this state and doesn't fully load: image

How to reproduce - part 2 (if you had luck and Ardour started)

  1. Try to get work done in Ardour. At some point it will either crash (close the window) or freeze (UI stops updating and sound is gone). Most of the time the crashes seem random. As of now, the only way I found to reliably get Ardour to freeze is to change the system volume while Ardour is playing back.

Additional info:

  1. The problems happen more often on non default (!= 1024) buffer sizes. For example when using a buffer size of 2048, with this command: PIPEWIRE_LATENCY=2048/48000 pw-jack ardour6 I feel like it is more likely to already freeze on startup.

  2. OS: Arch Linux

  3. Pipewire version: 1:0.3.29-1 (from arch repos) and master (431bcb68)

  4. I tested Ardour on original jack and it works stable with it.

  5. I currently don't know how to get useful logs for this, sorry. Hope it is easy enough to reproduce.
