Something weird also seems to be happening with the Cleanup tab in Big Sur (11.0.1). First time I have used Vinylstudio since updating. The split tracks waveform looks normal but the the cleanup waveform has gone, what I can only describe as, "blocky" and is really sluggish / jittery (basically uncontrollable) when reacting to the mouse when zooming in etc. I thought it was the dark mode to blame at first but switching to light mode, it's just as bad. Please help!
