In Adobe Photoshop, the updated Canvas Size dialog fails to record relative dimensions when recording an Action. This works correctly in 27.3.1 (Release), but is broken in 27.4.0 (Beta).

Steps to reproduce

Open any document.
Create a new Action (in the Actions panel).
Click Record.
Go to Image → Canvas Size…
Change the units to millimeters (mm).
Switch the size mode from Absolute to Relative.
Enter values:
- Width: X mm
- Height: Z mm
Click OK to apply.
Stop recording.

Expected result

The Action records a Canvas Size step with parameters:

With Relative
Width: X mm
Height: Z mm
Horizontal: Center
Vertical: Center
Extension Color: Background

Actual result (27.4.0 Beta)

The Action records a Canvas Size step with:

With Relative
Width: (blank)
Height: (blank)
Horizontal: Center
Vertical: Center

The Width and Height fields exist in the recorded step, but their values are not saved (empty).

Adobe Photoshop Version: 27.4.0 20260201.m.3398 df09e8f arm64 (beta, PublicBeta)

This is apparently a bug with the "Modern User Interface". You can disable that in Preferences > Technology Previews. That reverts to the old interface.

Thanks, that worked perfectly！

When I record an Action, changes made in Image > Canvas Size don’t seem to record the Height value correctly.

If I adjust the canvas manually, the difference is very small (around 0.04 mm). But when I run the Action, the error becomes much larger (about 5 mm), which doesn’t seem like normal pixel rounding.

Also, when I only change Image Size, the results are the same whether I do it manually or through an Action.

Since the Canvas Size height change doesn’t show up in the recorded Action, I think there might be a bug with how Canvas Size is being recorded in Actions.

Disable the Modern UI. Goto the Photoshop preferences on the "Technology Previews" tab in the dialog.

Uncheck the option "Enable Modern User Interface".

Disabled modern user interface, canvas size dialog was just fine as is. Needed the ability to record canvas size to adjust everything uniformly.
