I can see the problem, it's really weird. Maybe reinstall your RD but I only half believe it.
Another idea: completely re-enter your pieces since you have all the elements in memo - Bar summary.
I can clearly see the slight shift which begins after measure 45. But otherwise they generate perfectly well, I remain permanently in track view, and I did not notice your concern about "preheating" time, it responds perfectly.
Maybe could you send your tracks to Support@pgmusic.com if they have time to analyze them?I don't see anything in the entry that could cause a problem but there may still be a piece of 2023 code that went wrong.
