Certain actions move PS out of full screen mode in v.21.0.2

[jonathan.lipkin]

When I'm in full screen mode (by pressing f twice so there is no menu bar), certain actions move PS out of full screen to full screen with menu bar. Pressing f three times moves it back to full screen.

This happens when option-clicking on palettes on a secondary display. I noticed it when making clipping paths on adjustment layers, but option-clicking on any palette causes the behavior to occur. Command or control clicking has no effect. 

Not fatal, but quite annoying

Also, only seems to happen with certain image files

New issue with v.21 (didn't happen in earlier versions)

Mac Pro 2013 running high sierra.

Adobe added the new feature Zoom to layer, using alt/opt click. This has been causing a lot of conflicting issues with other features. Hopefully, they will correct this soon.

If you have Problems with Particular Actions changing  Photoshop Viewing mode from what you want. You should edit the actions and un-check the actions view steps that change screen mode. Clicking on Palette Options in palette options on your secondary display should not change Photoshop View Screen mode unless the option play an Action or runs a script. Actions and scripts can change photoshop view  screen mode.  They can also transform, resize and zoom. Action and Script automate some processing that effect how image display is done.  Adobe has made changes in the past that effect Action playing.  It sounds like you may have more than a single problem. Some steps must be changing Photoshop View screen mode from Fullscreen with menus to some other View screen mode.

Thanks, JJ. I wasn't refering to photoshop 'actions', ie prerecorded sets of commands. I was using the more general UX/UI term 'user action' - simply somethig a user does.

In my case, it's just option-clicking on a palette that changes the view mode. This is very clearly a bug in Photoshop

What Hardware and OS are you using.   I have CS3, CS6, CC 2-14, CC 2018, CC 2019 and PS 2020.  I have two or more displays withe some palettes on my second display.  I edit Images on my main display usually in standard screen mode in floating  windows.  Clicking on palettes in my second display never changes my Photoshop Screen Mode. It stays in, Standard Screen Mode,  Fullscreen with Menu or Fullscreen. What is displayed may change. However, with PS 2020 On my second display I only haves the following palettes one my second display. History, Actions, Layers/Channels/Path. In the past I had many more palettes on that display. However I map my Wacom Pen only to my main display when Photoshop is running. So many Palettes I could not address with my Pen.  PS 2020 Change Photoshop UI in many ways so  I setup a new Workspace for PS202 many palettes are docked in  Photoshop main window on the right on my main display. May pop-out from their docked Icons  Other are in tabs. Clicking on a Palette should not change Photoshop's Screen mode??? What is displayed may change.  I rarely use Fullscreen mode though. If you are being switch to Standard screen mode if could be I problem I would not encounter for that how I edit 99% of the time.

I just moved all palettes except toolbar to my second display in PS2020 switched to screen mode Fullscreen with menu. I have not been switched out of that mode  using palettes on my second display. So it may be a Mac Problem I use us a Dell PC you use a apple Mac.  Or the files that seem to fails may have problems or cause event handlers to run the could switch screen modes.

Correction - this behavior also happens on my laptop (mac pro 15" 2017) in photoshop 20.0.5.

Option clicking on a palette on the non-image display (on my laptop I use the 'main' display for palettes, on my desktop I use the 'main' display for images) causes a shift in full screen mode. Option-clicking on palattes in the 'main' display does not cause this behavior

As I wrote I use windows not a mac.  The only strange thing I encounter  with windows switching displays is on  my workstation that has three Dell displays two 4:3 1600x1200 displays and a 4K 3840x2160 middle display.  The 4k Display is windows display 2. I normally edit my images on the 4K 3840x2160 display in Photoshop main UI window. If I walk away from my machine with Photoshop up on my 4K display and some palettes on 4:3 display 1.  If the displays go into Power saving mode not sleep.  That machine never sleeps. It has Printers and disk the other network machine use. When I cause the displays to leave power saving mode the 4:3 display power up faster than the 4K display. And Photoshop seems to see this and switched Photoshop Main window to Display 1 its no longer on display 2. When it finally powers back up  I have to move Photoshop main window back to display 2.  On my other workstation I have Photoshop on display 1 and palettes on display 2 both are 1920x1080 displays. Photoshop windows and palettes stay put.
