Simultaneous jack clients glitches audio in one of them
Yesterday I was running Musescore (flatpak) and playing a sheet music, then I opened Spotify (flatpak) and put a song to play at the same time, when I pressed "play" Musescore audio started to glitch a lot. When I paused Spotify the musescore playback went normal again. Now what did surprise me was this: If I open OBS-studio this issue disappear and both clients can run without any issue.
