bug photoshop choppy

@28595393 ,

I've seen reports of issues on M2 (which did not occur on M1); we are currently investigating, with the first goal being to see if we can replicate the issue. As noted by another user below, similar hardware is not behaving consistently, so any more details about your operating environment would be helpful for us to narrow down the issue (eg, using many open documents at once? separate attached display? using any other apps at the time? Using any other plugins for Photoshop? What kind of file? using any custom color profile with the image? Does the issue happen with the first open file, or only if many images open? 

As you can see, there are many operating variables which could contribute to the issue.

@28595393 have you tried rolling back a version to see if things improve?

I have a very similar MBP as Andrew Beales 28  without any issues with Liquify or otherwise; something else conflicts with Photoshop. With a 16-bit, 125MB document, it is buttery smooth and instantaneous.

Try the following: 

1. Go to Preferences/Technology Preview and check "Disable Native Canvas" - Restart Photoshop. 
2. If you hold down the Alt key when you select Filter > Liquify... does it work correctly?

You could try running the Creative Cloud Cleaner Tool to remove all traces of Adobe software before reinstalling it (yet again):  https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

That didn't work. It's Adobe job to update and fix the issue. Adobe CEO need to take care about user's pain point. 

That didn't worked at all.. Still photoshop scrolling is choppy and liquify is slow and unrespoing a lot

Try logging into another Mac user account (you should make a new one); still choppy? 
Try starting up in Safe mode (hold down Shift Key when booting*), still choppy? 

* How to start your M1/M2 Mac in Safe Mode
On your Mac, choose Apple menu () > Shut Down.
After your Mac shuts down, wait 10 seconds.
Press and hold the power button until the startup disks and Options appear.
Press and hold the Shift key, then click Continue in Safe Mode.

Hi @28595393 

Go to Preferences/Tools and disable flick panning and overscroll - does the issue still occur?

Are you using only a mouse or do you also have a graphics tablet/pen?

When Photoshop crashes, this is the first thing to do, try resetting your Photoshop preferences. Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (macOS) immediately after launching Photoshop. You will be prompted to delete the current settings. You can also reset preferences upon a quit if Photoshop is running by going into General Preferences>General>Reset on Quit.

(macOS only) Open the Preferences folder in the Library folder*, and drag the Adobe Photoshop CS Settings folder to the Trash.

This action only affects the items found in the preferences dialog box. Numerous program settings are stored in the Adobe Photoshop Preferences file, including general display options, file-saving options, performance options, cursor options, transparency options, type options, and options for plug‑ins and scratch disks. Brushes (and lots of other setting) are not affected by the above instructions for deleting preferences. You may wish to make a screen capture of the settings in the Preferences dialog to reset them prior to deleting of this file.

*To manually delete Photoshop preferences:
Quit Photoshop.
Navigate to Photoshop's Preferences folder:
macOS**: Users/[user name]/Library/Preferences/Adobe Photoshop [version] Settings
Windows 10: Users/[user name]/AppData/Roaming/Adobe/Adobe Photoshop [version]/Adobe Photoshop [version] Settings
**Note:The user Library folder is hidden by default on macOS. In the Finder, hold down the Option key when using the Go menu. The library will appear below the current user's home directory.
Now you can drag the entire Adobe Photoshop [Version] Settings folder to the desktop or somewhere safe for a backup of your settings

If that doesn't fix the issue:
Go to Preferences > Performance... and uncheck Multithreaded Compositing - and restart Photoshop.
Still crashing? 
Go to Preferences > Performance... click Advanced Settings... and uncheck "GPU Compositing" - then restart Photoshop. Still crashing?
