There is a lag on all selections in Illustrator 28.2. When I select any item I literally have to wait 2-3 seconds before I can move my cursor, else the selection "sticks" to my cursor and moves with it until I click again to drop it and then I have to ⌘Z to send the selection back to it's intended location so I can make the changes I need to make. SUPER FRUSTRATING.

I have a new Macbook Pro with loads of RAM and never had this issue until the latest Illustrator update.

Thank goodness I have Affinity Designer installed, because when I get too frustrated with Illustrator (my favourite app since 1994) I have a backup.

Since Creative Cloud came into existence I've noticed more and more glitches in the Adobe software. Perhaps too many updates too soon, or not enough quality control or testing before sending updates out? At some stage the software will have to be rebuilt from the ground up like Affinity did, instead of building on old frameworks.
