In the new 2025 version of illustrator the pencil tool is not as acurate as before?

Hi everyone,

I am making vector illustrations and perfecting them with the pencil tool as I always do.

But in the new 2025 version the vector drawings are not changing as acurate as before.

They are just jumping everywhere and are not nearly changing like I draw the line.

I have put the fidility totaly to the accurate side but still it is not accurate at all.

Did something change? Do I need to change anyting in the settings so the pencil tool will react like before?

Or is this a bug in the new illustrator version?

Thank you in advance,
