Does this happen with all clips or only specific ones? There are some breathy sounds and cymbal crashes that sound scratchy to me when the pitch is adjusted but I'm not sure if that's what you're referring to.
Do you have a sample of a pitch-shifted clip you made before the latest update? Listening to that and how it sounds to make the same adjustment now would be the ideal test of whether something has changed.
