Severe object dragging lag in Illustrator 30.8.2 after macOS 27 update
Environment: macOS 27, Adobe Illustrator 30.8.2
Problem: Since upgrading to macOS 27, dragging objects with the mouse or trackpad no longer works smoothly in Illustrator. The cursor moves normally, but the selected object remains stationary for several seconds before suddenly jumping to a new position.
Steps to reproduce:
Open Illustrator and create a new document.
Draw a rectangle or create a text object.
Select the object and attempt to drag it with the mouse or trackpad.
Expected: The object follows the cursor continuously and without delay.
Actual: The cursor moves normally, but the object does not respond immediately and subsequently jumps to a different position.
Additional diagnostics:
Occurs with text, rectangles, and other objects.
Occurs in all documents, including new ones.
Both mouse and trackpad are affected.
Moving objects with the arrow keys works normally.
Dragging in other macOS applications works normally.
Disabling GPU Performance does not help.
Disabling Smart Guides does not help.
Restarting Illustrator does not help.
Updating Illustrator to 30.8.2 does not resolve the issue.
No Wacom drivers or third-party window-management utilities are installed.
Checking Input Monitoring permissions did not resolve the issue.
Suspected cause: Regression in Illustrator's mouse/trackpad drag-event handling following the macOS 27 upgrade.
Please investigate this as a potential macOS 27 compatibility issue.
PS: no such issue in Photoshop.

Gernot, would you mind recording a small video and share the full specs of your machine?
