P: PS 27.6 Canvas size fields, units & increments are broken when MUI is used

The recent 27.5 release got updated Canvas Size modal, and it has several bugs that affect my workflow, which requires gradual pixel-perfect changes of canvas size in various directions (my units are pixels most of the time).
I use relative changes to canvas size, so ‘Relative to current dimension’ checkbox is ON for me most of the time, and in this case the bugs I get are:

  1. Canvas Size modal opens with default values of width and height set to 1 pixel. Should be 0.
  2. The width and height inputs do not accept 0 value — it gets reset to 1, meaning if I want to change canvas size in one direction, anyways I’ll get 1 pixel added to the other.
  3. It’s not possible to set negative values now, which used to work before, and at times it’s more convenient and precise way to ‘crop’ canvas, rather than using the Crop tool.
  4. The values step now is 0,01 pixel, which is meaningless in most scenarios. It used to be 1 pixel, and it should be, as it allowed to use keyboard up and down arrows for quick pixel perfect adjustments.

See attached video demonstrating all 4.

What I discovered later: if I uncheck ‘Relative to current dimension’ checkbox and check it again — I get the right behaviors (except bullet 4 with increment step). Those all are apparently bugs to be fixed.

System:

Photoshop 27.5.0
macOS 26.3.1 
MacBook Pro, 16-inch, 2023

      Every Tool set is a mess. A while ago I had to start using Help to find and use Tools like Magic Wand, which I could add to the Tool Side Bar, but it comes and goes. Then the Elipse Tool is no longer nested under the Rectangular Selection. I used Help to regain use, but cannot use Fill tool. View Layers comes and goes and is difficult to find and restore. New floating tool options cover up each other and dominate the work area. I had to completely abandon a project today for lack of Photoshop functionality.

      Hi ​@philipf94266473, we’re sorry to hear that.

      For the issue with the nested tools, try following this link: https://helpx.adobe.com/photoshop/kb/bringing-back-tools.html

      For workspace related issues, try resetting the workspace by going to the Window menu, then Workspace, then Reset Essentials. This forces Photoshop to rebuild the panel layout.

       

      Let us know how it goes.

      Thanks, 

      Nikunj

      I have the same problem as BrentBristol, everything works properly when recording the action but when I play it, the canvas size doesn’t change and when I look at the action there is no target size saved, the field is blank. (The canvas color does seem to work properly, however.)

      Discovered that a work around was provided for this issue several months ago.by user Ged_Trayner.  Uncheck  “Enable Modern GUI” at File/Preferences/Technology Previews and restart Photoshop.  I was able to get Canvas Size to work in actions after following this advice.

      Thank you https://community.adobe.com/members/ged-traynor-1848701

      I have a similar issue when trying to record a change of Canvas Size in an action.  While recording the canvas size step the requested size is applied, but it is not recorded for subsequent playing of the action.  To illustrate I have made a very simple action that only changes the canvas size.  Screen shots showing the original canvas size, the change in canvas size, and the lack of dimensions recorded in the action are attached as well as the operating system information.  The requested canvas size change is applied while recording, but does not work when replayed on another image file.

      A rajzvászon méretének növelésére nem enged  0 értéket beírni csak 1 illetve annál nagyobbat, ezért újra meg kell vágni a képet

      Hey, @artemm75338422. Thanks for bringing this up. I've checked your comment in another thread. Thanks for collecting these issues in one place. I can confirm that the team is aware of all four of these points.


      I've added the bug details to this thread, but I'll have to move it to Questions for now, because I can't merge the same post to the 3 parent/primary threads we have for these issues.


      Thanks!
