BUG - crackling in playback - not on the recording

Since the update before last, I’ve had crackling in the first maybe 10 seconds of playback that is not on the recording, and not a fault with my headphones (I tried it with various types).
It happens no matter at what point in the track I start playing back, I get crackle for maybe the first 5-10 seconds. It makes working on tiny sections of audio almost impossible. If you repeatedly play back the same bit, the crackle changes each time and eventually stops, so it’s almost impossible to tell if it’s real crackle on the recording, or just this bug.

Anyone else?
