Thanks for checking! Testing and cleaning the effects is an ongoing efford and recently a lot has improved already. I'd say we can close this report as it is generic about ladspa plugins. Feel free to reopen or create a new report if you provide an actionable list with effects that work / don't work so we can fix this.
