In the latest version of Photoshop, ruler visibility (Cmd/Ctrl+R) does not persist globally. Rulers must be re-enabled repeatedly when opening existing documents or switching between files.
In earlier versions of Photoshop (e.g. CS6), ruler visibility was a global UI state and remained enabled across all documents and sessions. The current behavior appears to be a regression in usability.
Steps to Reproduce
Enable rulers using Cmd/Ctrl+R
Open an existing document where rulers were previously disabled
Observe that rulers are no longer visible
Repeat with multiple documents or after restarting Photoshop
Expected Result
Rulers remain enabled globally across all open documents and sessions.
Actual Result
Rulers must be manually re-enabled per document.
Impact
This causes unnecessary repetitive actions in professional workflows that rely on consistent measurement and alignment across many files.
This behavior worked differently in earlier versions and multiple users report similar issues.
