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

I have a 34" ultrawide monitor so my workflow is done using a large main window and enabling the secondary window (F11) set as the gallery browser. For all this time, until I installed the new version 12.3, the secondary Window would close if the main one lost focus, like if I switched to a browser tab or something else, but then would come back once the main window was back in focus again.

As of the latest update to LRC, the secondary window no longer returns and I have to manually re-enable it. This is highly annoying and adds a hindrance to the workflow as I find myself constantly having to press F11 to bring it back.

1: It was bad enough that the secondary window closed on main window focus loss in the first place.

2: It's now a major issue that the window does not return on return of main window focus like it used to.

Can both of these bugs be resolved please? The first point has existed in forever, and I recall posted on other forums talking about it for years yet Adobe don't seem to care to sort it. Any chance this can finally be sorted?

For reference, the first issue is discussed here: https://www.lightroomqueen.com/community/threads/keep-secondary-display-showing-even-when-moving-to-another-app.35410/

System details:

OS: Windows 11 Pro

CPU: 12700KF

RAM: 64GB

GPU: RTX 4090

GPU driver: 531.61 Studio

I'm not a Windows users but the reports that I've read here would seem to indicate that keeping the GPU drivers up to date has become quite crucial.

As Adobe is switching more operations from CPU to GPU with recent releases, it may very well be that something that "just worked" before needs a GPU driver update, so that's something I'd look into first.

Nach dem Upgrade auf 12.3 funktioniert die F-Taste nicht wie gewohnt. Beim ersten drücken der F-Taste wird das Vollbild kurz angezeigt und springt nach ca. 1 Sekunde wieder zurück. Drückt man beim gleichen Bild die F-Taste erneut und hält sie gedrück wird das Bild länger angezeigt.

System: Win 10 Pro und Nvidia GTX 1150 ti
