OK, that's reassuring, even if the "twice the events" stuff isn't what you'd expect. We at least know this is a separate issue, and that this patch on top of -rc1 brings you back to the 5.15 behaviour. I'd expect it to be the case for the other platforms as well. Thanks, M. -- Without deviation from the norm, progress is not possible.
