Neither Wafeform12 nor Waveform11 nor reaper have this issue.

This is likely the same issue as

Ardour delegates background processing to JACK, and those those threads cannot be stopped due to a recent bug in glibc that arch ships.
It s already fixed upstream:

meanwhile you could downgrade glibc (as mentioned in the forum thread).
