Hello, I am hoping for some help with this bug that I have been experiencing for a few months. I am unsure when exactly it came into effect.
Common lags I am experiencing:
- Brush slow to catch up when using the Healing Brush Tool
- Selecting source point with Healing Brush and Clone Stamp Tool
- Increasing/decreasing brush size using [ and ] keyboard shortcuts
- Zooming in and out of the document
- Using Hand Tool to pan around the document
- Using Pen Tool
- Switching between tools
In trying to fix these lag issues, I have uninstalled Photoshop, deleted all preferences and reinstalled it. I have also installed older versions with no luck.
After installing Photoshop again, I didn’t have my workspace preferences anymore and the problem seemed to disappear. After creating a new custom workspace laid out how I like, the lag came back instantly.
I am a professional retoucher and I have utilised customised workspaces for ease of use for many years. I usually set up an external monitor with all my most frequented panels laid out like this, for example:

Please excuse the blurred sections, just hiding client info.
As soon as I switch back to a default workspace, such as “Photography” (even with the panels moved around a bit on an external monitor), the lag disappears.
Running:
Adobe Photoshop 25.3.1
macOS Sonoma - Version 14.2.1
Mac Studio - 2022
Apple M1 Ultra
128GB RAM
4TB Storage
Apple Studio Displays
Wacom Pro Tablet
Any help at all would be greatly appreciated, it’s really slowing down my workflow.
Thank you
