Automix: Sync + Tempo Blend still looses sync

This is similar to another problem we are discussing in this section, which has not been solved yet.

If Tempo Bland is enabled, there is 0.1%… 0.2% sound distortion when you start mixing… I wrote about it. Same thing when you go from 99.8% to 100%.

Can’t anyone repeat what was described in the other thread? I’m not the only one who has this problem.
Is someone solving these issues?
