My operating system is Catalina. 10.15.7
Illustrator CC 2021
Apple Mac 2020 27". 40GB RAM

I have an issue with the whole artboard juddering across the screen when I move an element in illustrator. The juddering can last 60 seconds or more.

I am a packaging designer and use a WACOM. This only happens when the WACOM is in use, to the point I have to physically unplug it and use a mouse (not ideal) to stop it happeneing. I have spoken to WACOM who tell me they have contacted Adobe, but the issue still isn't fixed.

Can you assist?

Thanks

Claire
