Volume automation artifacts

Hi everyone, upgraded today to Cubase 13 (from 11) and I’ve noticed a weird behaviour that never happened to me before.

I tend to use volume automation for “ducking” effects, and quite steep automation curves for that - never had a problem with v11, but now on v13 if the volume automation curve happens within a 1/128th time (from 0 to -inf) it causes a clicking noise on that track - happens on group tracks or individual.

For context, I use this mainly for bass/kick relation as I prefer this to using a compressor in some cases.

PS: added a video showcasing what I mean, gentle slope no problem, when using a more agressive curve click happens. Didn’t happen before.

Any ideas as to why?
Thank you!
