when clicking in the photo with clone tool, it clones entire photo

Hi all, could you share a screen recording of your workspace as you see this issue so we can try to notice what might be the cause. Make sure to have the latest Ps Beta: Adobe Photoshop Version: 27.12.0 20260927.m.3691 5144a9c  arm64 (beta, PublicBeta)

1. Try resetting Prefs for the Beta:
/Users/yourname/Library/Preferences/ Photoshop Beta Settings (Mac Ventura)
/Users/yourname/Library/Preferences/Adobe\ Photoshop\ \(Beta\)\ Settings (Mac)


C:\Users\user name\AppData\Roaming\Adobe\Adobe Photoshop (Beta)\Adobe Photoshop (Beta) Settings

Launch BETA Photoshop While Pressing The Keyboard Shortcut
With Photoshop closed, press and hold Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and then Launch Photoshop the way you normally would.

2. It may help if we could see your Photoshop beta System Info. Launch Photoshop beta, and select Help >System Info...and copy/paste the text in a reply.  

Thanks,

Cory - Photoshop Product Manager

That happens when you have Show Overlay checked in the Clone Source panel

I would have expected Resetting to return that to its default, but I just tested and it stayed checked.  I’ve never really worked out what the purpose of Show Overlay.  Anyone know?

Currently experiencing the same problem, had some progress with resetting the tool settings, but it persists
