Unable to lock aspect ratio when using the Scale tool
In version 30.1, scaling a graphic with the Scale tool while the aspect ratio is locked no longer works correctly. When holding the Shift key and dragging the mouse at a 45° angle, the graphic snaps back to its original size instead of maintaining proportional scaling. This breaks the previously working workflow for scaling graphics while preserving aspect ratio.
Steps to Reproduce:
- Select a graphic to scale.
- Choose the Scale tool.
- Click and hold the mouse button on the graphic.
- Hold down the Shift key and drag the mouse at a 45° angle.
Observed Result:
The graphic flickers rapidly, alternating between the original and scaled sizes, and ultimately snaps back to its original dimensions.
Expected Result:
The graphic should scale smoothly with the aspect ratio locked, showing an accurate live preview throughout the transformation, as in earlier versions of Illustrator.

This is a known problem and it’s not new, sadly...
To workaround it, please disable the 'Transform Tools' option in Preferences > Smart Guides (or just disable Smart Guides, if you can).
