Thanks for reporting that.
There was an aliasing issue reported on this thread.
Actually, that was really well-spotted @spunktsch. I first thought that the issue was solved with the wisdom files and following updates, but that is not clear from what I read in the thread.
I just checked the plugin and there’s not yet the oversampling switch there. I’m not sure what is the status, but I will just ping @Jan here to let us know
