P: KBSC [ F ] for full screen returns to regular view when second screen is active

Hello,

I tried both methods, but no change. How can I upload the file?

Best regards Thomas

This is a new behaviour/issue:

I am using Lightroom Classic 12.3. on Windows 10.

Steps to reproduce:
1) Show Secondary Display (press F11)
2) Switch to any other app, secondary window dissapears as in the previous versions
3) Switch back to Lightroom, secondary window DOESN'T appear, but it did in previous version of LR

I guess it might be a newly introduced bug as this behaviour doesn't make sense to me.

(BTW I wish it wouldn't even disappeared in the first place, but that is another story - some toggle would be great too)

Same problem with M1 Mac studio, two screens, only since upgrade to 12.3.
When I minimise LR and return to it, or my computer sleeps and wakes, or when I hit F for full screen, then the secondary window on which I have LoupView jumps back to the first screen, over the main window. This is a minor annoyance if I'm not using full-screen, but when using full screen, it's extremely annoying as I can't get to the main window to fix the problem.

Hi Adobe-Team,

I have one monitor and I'm using the secondary view window. If I press F11, the window is shown.

When Lightroom looses focus, the window disapears. Prior to v12.3 the window appeared again, when Lightroom got back the focus. In v12.3 the secondary view window is not shown again and I have to press F11 again. This happens everytime, Lightroom looses focus.

When I switch back to 12.2.1 the application is behaving, like expected: the secondary view window is visible, as long as Lightroom has focus, hidden, when it losses focus and shown again, when Lightroom gets focus back. If I install 12.3 the secondary view window will not show again, after Lightroom lost focus, until I again press F11.

I can easily reproduce this:

1. I open Lightroom
2. I press F11 to show the secondary view windows
3. I click on an emtpy area of my taskbar or, if visible, on the desktop, so Lightroom looses focus
4. now the secondary view window disappears, which also happened prior to v12.3
5. now I click somewhere in the Lightroom window to give back focus
6. now the secondary view window is not shown, prior to v12.3 it then was shown again

I'm having this issue as well - please resolve soon.  Thanks!

My PC has two displays, a set of 24", HDMI connected, Dells.  I've always operated with Lightroom Classic in this fashion, with my editing screen on the left and the grid view on the right, so I can see all of my thumbnails. 

Up until v12.3, if I hit the "F" key to put the left screen in Fullscreen mode, it worked w/out issue.  After upgrading to v12.3, it just flickers once and then reverts back to the normal view.  However, if I hit "F11" (whihc toggles the second screen on/off) and turn the second Lightroom Classic screen off, "F" works just fine.

I tried contacting Adobe's support via email and chat, but neither channels worked, so figured I'd give it a try here and see if anyone else has run into this issue.

Hi. After latest update I can't turn on fullscreen preview when Lightroom is working on two monitors. When I press "F" key, it fullscreen preview just blinks and disappears. I need to disable dual screen by pressing "F11" key and only then I can preview photos on fullscreen. Is there any fix to this issue? I'm on Windows 11.

Hello, 
I am facing a bug in LRC12.3.
I checked that it is not in LRC12.2.1.
When I try to open an image in full screen (command F), the fullscreen image appears then vanishes instantly. The behavior is correct as expected with the previous version (LRC 12.2.1) that I re-installed to check.
Tech data : Win10 Pro 22H2 (x64) up-to-date, AMD Ryzen 7 3700X 8 cores, 32Gb Ram, NVidia RTX2070Super (last studio driver), 2 screens.
LRC opened on Eizo Screen with grid view and a few images are selected, 2nd screen displays the Survey (N) view. At that point I want to display the individual images in full screen to see their details. 
It worked fine till version LRC 12.2.1. It is broken in LRC 12.3.
Can you help me. This is a major function for me when I am editing my new sets of photos.
Regards,
Patrick Huguet

@Treefrog Photography  Yup there are multiple ways to trigger the issue, basically anything that takes focus away from the main window will trigger the closure of the secondary window.

A scenario that causes this error every time.

I have an ultra wide screen so physically both screens are on the same physical device.  One screen is my library and the other is my loupe.  Any time I select an image and click on "edit in photoshop 2023", it immediately closes the loupe window and then launches Photoshop.
