Crashes when toggle to sounds and activate Arppegiator - Linux - Debian 12 - X11

I got Audio Engine Crashes 3 times in a row playing around with SoundBox.

  • Create new Source Crash, 1 times crash
  • Toggle to Sounds, 1 times crash
  • Activate Arpeggiator, 1 times crash
  • can’t reproduce but it happens.

i read about the X11 Things and this Tool, but cant find original post
