Library with lag

Hi @Luiz_Raffcom1051 could you share more about your workflow, what you are doing or path you use to get to this issue?  Do you see the same thing with Ps realease or just Ps beta?

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

Do you mean that it is slow to fill the panel, or slow to move the panel?

How many files/objects do you have in your CC library, and what is thir typical size?

Could it be accessing your files in your Adobe cloud storage space?  What is your internet connection like?
