I did actually notice lots of stutter yesterday when running the audiovisual
demo (PR) in Release on Ubuntu 22 with audio playback routed to the front
output of my system. I will try to see if this makes any difference on my end.

Ok, sounds good. To avoid any confusion: I removed libjack
as a dependency for the release of 0.7.5 because it's not default (installed) with Ubuntu 24.04. I don't think that's what you used in the past (default often isn't jack) but good to know. Also: You might want to use a Low-Latency Kernel (Ubuntu Studio). and benchmark with and without the PaAlsa_EnableRealtimeScheduling
enabled.
When going over the ALSA docs for portaudio I noticed you have to explicitly enable real time scheduling:
We should turn it on, because it's (implicitly?) enabled on all other platforms according to @stijnvanbeek - resulting in less frequent drop-outs, although me personally have not noticed any.
