If I had to guess it's likely do your abstractions (docker) and possibly xwayland.
The former also voids any realtime capabilities and is unsuitable for any pro-audio work. You will likely also experience dropouts and unaligned audio when recording overdubs.
I expect the official binary natively on openSuSe does not have this issue. |

@x42 Thanks for your quick response. Now that you mention abstraction: I was able to reproduce the reported behavior with the Ardour Flatpak. But if the downside of containers is lack of peak hold, I shall accept it. Subjectively, so far, with Ardour in Distrobox the latency and dsp performance are the same as or better than on my previous Debian 12 installation with Ardour installed directly onto the base system (using the same hardware as I use now). To be fair, back then I was using jack2 alone instead of pipewire and other magic. MIDI recording works like a charm and audio is responsive as well, with only few xruns (if I use lots of tracks and dozens of plugins on each of them) and all of this while energy-saving mode in GNOME is active. I don't know, how exactly you made Ardour so efficient, but I love it. Thank you for that btw. :) |

We do not support Ardour Flatpak. That is provided by a 3rd party. Please contact them about it. |

Do I understand correctly that did not have this issue on the same hardware when you used debian? meters moved smoothly there with Ardour 8.6? |

I'll let them know. As for the Archlinux build, I'll report to its maintainer as well. I can not recall, whether I used this option on Debian. But Ardour Debian package was at version 6.9 (nice) and I do remember experiencing occasional FPS-drops (when scrolling in editor or mixer window), to which I got used to, believing it was due to project size or GPU. It still happened, when I switched to openSUSE MicroOS (using Ardour 8.x (something earlier than 8.6) in an Archlinux Distrobox here, too), until I replaced the graphics card (an AMD Radeon R7 240 or 250, I believe). After installing the RX 7600 XT, overall GUI responsiveness improved a lot (in any program), continuing to be even better in openSUSE Aeon, after I upgraded from MicroOS. |

For various reasons, I now switched to another base system again. And I'm happy to report, that Ardour appears to run quite nicely on CachyOS (I only tried the distro's own package, optimized by the maintainers via some compiler flags etc.), with metering working mostly fine (except for a small glitch, that leads to a statically fully lit meter on my Behringer X-Touch for deactivated tracks in Ardour). As CachyOS refrains from encrypting the whole installation by default, it's faster than Aeon and I Ardour now shows way less notifications about my drive being too slow, when using audio files in projects. Also, I'm feeling embarrassed about mixing things up, but I need to correct something wrong I wrote before in this thread: I did not use Debian 12, but MX Linux 21 "Wildflower" and that distribution was based on Debian 11, I believe. |
