Crop Tool Lag

[radhamadhava11]

I'm using Mac OS Big Sur 11.7

I have a late 2014 5k iMac, with a 4 GHz intel i7, 32 GB of 1600 MHz DDR3, and a 4 GB AMD Radeon R9 M295X video card.

The crop tool is laggy. I select it, and try to drag the corners of the preview area, and it lags, jumps around and is imprecise and slow.

This is odd, as making a rectangular selection is smooth and works fine to then select Image/Crop.

Also in Adobe Lightroom the crop tool works smoothly, with it's preview overlay.

Why the disparity?

I haven't seen this bug anywhere else listed in your forums or elsewhere online, so I wanted to report it now, to ensure that future updates have it resolved, as I don't want to have to buy a new computer in order to update my OS, in order to run the latest version of Photoshop that's not BETA, or an old version that won't recieve new features.

Thank you!

Let's make sure we're in a default state and there are no stale settings somewhere:
Restore your preferences using this manual method:

Does it work correctly?
If that doesn't solve it, you can quit Photoshop and put the Settings folder back.
