Zooming ,Scrolling and Hand Tool Sluggish Photoshop 20.0.6 Windows 10

It's still laggy with the last version. v24.0.1.  Anyone has a solution ?

I think I found the problem and the solution.
After a lot of tests, I figure out that problem ocourr when the Rulers was on. When I deactivated Rulers (Ctrl + R), the lagging was gone. But it was a temporary fix. So, I found another fix: I just uncheck that option on preferences and voilá, Photoshop's slow when zooming is gone.

This is also happening to me now, the thing that makes no sense it that if I use the scroll bars, it's instant, yet if I use the hand tool (spacebar) to move around there's a couple of seconds delay in using all tools.

I have a wacom, but I'm currently using a normal USB mouse adn this is happening.

I don't get why the scroll bars would be instant, but the hand tool using space bar would have a delay.
I'm using the latest version of PS 21. (Updated through CC app on WIndows 10)
I've yet to use PS 22 though, as I'm in the middle of a job and don't want to switch part way through

I'm on the latest PS build, windows 11 and this is still a bug - can we get this fixed please?  Super annoying to have to 'scroll all windows' just to get panning to be smooth.

it happens to me when i'm zoomed in and try to use two-fingers to scroll around the image. if i use the navigator window and click around with the red sqaure it moves fine. 

how can this not be addressed yet?

Same thing here. We get serious lag with the clone tool. saving files, closing files, etc. And it's across all versions of Pshop we have from 2019, 2020 and 2021. It's about a 5-10 second lag and kills productivity. Makes working with Photoshop so frustrating as Affinity tries to lure us away.

Seriously, what's the fix Adobe? Don't say creating a new user account or wiping our computers or re-installing the program.

This is still a bug and hasn't been addressed by Adobe - March 11, 2021.

I can absolutely comfirm that this issue is caused by the Navigator panel being open.  I've been using Photoshop professionally for more than 20 years and to have performance bugs causing these sort of performance issues is unacceptable. Your older versions performed flawlessly.  I run PS on a dual display workstation and have always had an open Navigator panel on the second display.  It's an 'always on' full view of whatever image I'm working on and it allows me to quickly jump to anywhere on the image without having to use bird's eye view which is nauseating to use.  It's been a great workflow for a very long time now.  Adobe please stop 'improving' Photoshop by breaking things that work perfectly otherwise.  Also, please get this fixed asap.

Super annoyed that PS is getting buggy and many tools are laggy.  The hand tool has a slight initial freeze everytime I use it.  For those of us who have been using PS for 20+ years we shouldn't see tools getting worse in terms of performance.

Threadripper 3790x workstation running the latest version of Windows 10.  GTX 1080 gpu (x3). 128GB memory.  I shouldn't be seeing lag.

Where I'm seeing lag with other tools...

- stamp tool / healing brush (had to turn of preview in selection area to get the speed back)

- the 'new' pen tool is laggy where the old one could lay down and manipulate points in real-time

- gradation tool lag
