Spectral layers Extension slow edit behavior

Can someone let me know if this is normal extension behavior with Nuendo. Every time I edit something using extension or specifically in the current case spectral layers. Editing anything that now is on the track that contained the edited clip seems to carry a delay between when pressing the mouse and when editing? Real pain and forces me to bounce down the clip and remove extensions.

Wondering if anyone is experiencing this. Thanks

Yeah, it’s annoying.
The ARA protocol needs some improvements.

Okay thanks @Fredo , was going to investigate deeper in case it was my system behavior.
