gradiant tool

Hi @Paula26859347un3n sorry to hear you are having issues.  Could you share some screenshots or video of what you are seeing for the team?

Try resetting Prefs for the Beta:

/Users/yoourname/Library/Preferences/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.

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

Thank you,

Cory
