Interesting. I suppose I’m going to have to try out Cubase 13 to see if they’ve actually fixed it. As I said earlier, I did ask them if they had in 13 but they ignored that part of the question. I hope they have, but I’m not optimistic; whether it works or not does seem very randomly dependant on the source so maybe you’re right but I’d like a tool that worked on more than just perfect saw waves if so!
