  3. After that, uncheck “Enable Native Canvas Rulers”.
  4. Check if it fixes the Adobe Photoshop lag issue when using the Alt key.

FIX 2: Use Third-Party Tool

Some users were able to rectify this issue by using a popular third-party open-source tool called Apssistant. You may read its usage instructions and download it from GitHub and then see if it resolves the underlying problem or not.

FIX 3: Downgrade to Old Version

For some users, the issue first came to light right after they updated the software to version 23.2. So the best course of action is to downgrade the app to the earlier stable build. Here’s how it could be done:

  1. Open the Creative Clouds app and scroll to Photoshop.
  2. Then click on the More (…) button next to it.
  3. After that, select Other Versions from the drop-down menu.
  4. Now click on the Install button next to the app version 23.1.1.
  5. The older build of that app will now be downloaded and installed onto your PC.
