Hey again! I’ve got myself a Pop OS install on an old laptop, and after playing around for a bit I couldn’t reproduce any problem like you describe.
Would you mind giving me a bit more details? Namely, what’s your operating system and hardware spec? Were you doing anything specific in the moment it started to get crunchy? Any particular instrument, effect, filter and volume setting? Can you reproduce the issue or was it a one-time thing? Does it happen with different patterns after some time or is there anything that they have in common?
Details like that will give me a better starting point to keep looking, and maybe other users would then be able to confirm. If you have a GitHub account, I’d appreciate this info to be provided as a report there: https://github.com/YuriSizov/boscaceoil-blue/issues
This helps keeping track of every issue in one place. But also don’t feel like you have to do all this work. I’ll be testing it on Linux more now, and may end up repeating your experience at some point with my tools at the ready.
Thanks in advance, whatever you decide!
