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

Hello Adobe, 
Any news about a fix to the fix of 12.4?
There are still bugs on the Full Screen feature after the 12.4 fix.
The full screen view is randomly loosing the synchronisation with the other views, and doesn't display the currently selected image.
Last time I reported that was April 30th (nearly 3 months and nothing happened).
Maybe it's time to give a look or to open a new thread for that topic.
Remainder of the situation:
- main screen : grid view. I select several photos (5 to 50)
- secondary screen: shift-N (Library Survey view). Displays the selected photos.
Activate full screen so I can see in full view one of the selected photos (that one is choosen either with keyboard arrows or by clicking on the secondary screen). 
After a random time "clicking on the photos", the full view is stuck on one photo, then displays the previous one that I chose, not the current one. So if I don't notice that LRc is messed and I change a label, I am affecting a wrong photo, not the one I think I am tagetting. That's terribly messing. 
I can't ant longer trust my tool;  I can't concentrate on photo editing as I must check what is dooing LRc in my back. It's really painful. 
And after 3 months, no news! 
Could someone update that status? Please !

for @Ilya30865534yqrt : only the main title on this topic is fixed and more bugs about "full screen" have been reported about the supposed fix.
So the subject is far to be closed. Sorry

Fixed in 12.4 update

Ah yes, should have checked that. Did so now and indeed, full screen on main monitor stays in sync with grid on 2nd when using arrow keys to select next or previous image, including when that means next or previous row. When changing rows vertically with arrow keys, the full screen will lag one step behind again, like when using mouse clicks.

I'm seeing something similar.  If I have grid view displayed on secondary screen and full view on primary screen, clicking on images causes a lag as others have described.  However, if I advance on the grid view using arrow keys, full screen is coordinated; it's only mouse clicks that are out of sync.

On my system, what happens now can be described as "full screen view on main monitor lags behind one image selection on second screen".

Hence, no change on the first selection of another image in the Grid View on the 2nd screen.

After that it does update with every new selection, showing the previously selected image.

Same problem here - second screen clicks/selections are not in sync with main display. Also not immediately reflecting modifications to develop settings.

"Problem: after several clicks, the full view on the main screen doesn't follow (is not updated by) the selected pic on the second screen. More than that, if I select another one, it will display the former one that has been selected, not the current one."

I have the same issue.

Addition to my last post:
while the full screen view is not automatically updated by moving the focus to another pic, if I close the full view then resume it (so, pressing F key twice), the full view resumes to the correct pic.

Hello, I can confirm that this issue has a correction... but it is not a fully satisfying one. 
I am now sure that the bug was related to a poor "event stack management", and it is not completely fixed.
Explanation:
- config = 2 screens. Main one with Grid view. I select some photos; one is mainly selected. Secend screen in "N view" (Ensemble in French). My grid is a folder wich is filtered by labels (yellow in my case).
My goal is to choose wich photos I promote to green (key 😎 or remove the yellow label (key 7).
So the actions:
on my main screen I want to display the main selected pic in full screen (key F). On the second screen I want to go to the selected pics, one by one so they are displayed full screen on the main screen.
Problem: after several clicks, the full view on the main screen doesn't follow (is not updated by) the selected pic  on the second  screen. More than that, if I select another one, it will display the former one that has been selected, not the current one.
This is really messy ! I CANNOT TRUST what I see, as I am acting on the wrong photo in that case.
So I am convinced that the problem is related to the management of the "Windows Event stack" where every mouse click,or key press is sent before beeing managed by the appropriate functions. Normally, when an event is fully served, it has to be erased from the stack. I supposed that there is a misfit and either some events are erased too soon or not erased when needed.
Best regards,
