weird thing with -verbose:gc

So I with my audio project, I’m getting some glitching: it crackles every now and then.
CPU usage is about 15% of one core, so I thought maybe I’m generating garbage somewhere and enabled -verbose:gc.
It’s the damnest thing: the glitching is gone completely with -verbose:gc enabled!

Does anyone have some explanation for that? I sort of expected more the opposite.
According to -verbose:gc, the GC never kicks in (unless I start moving stuff around in the GUI, but that’s sort of expected)
Does -verbose:gc actually influence the GC’s behaviour somehow?
