Problem: Lightroom 'Close' and 'Restore' buttons vanish in full screen mode in macOS Mojave

  • Updated 2 months ago
When Lightroom Classic is placed into full screen mode in macOS Mojave, the bar that houses the 'close' and 'restore' buttons, bugs out and gets stuck behind the apple menu bar. Pressing Shift+F or changing options from the menu does not work, as is suggested in many forums. Only thing that can be done is to quit the app and re-launch.

This issue is triggered either by clicking on a different module within Lightroom or, waiting around 5 minutes.  No other applications are affected.  I have also re-installed to macOS High Sierra and tested for several days, the issue is not present there.

I have posted a video showing the problem.

This a constant issue for me. My work-around is to hover the cursor at the bottom of my screen until the dock pops up, right-click LR and tell it to minimize, so I can see my desktop.

I have reverted back to High Sierra for now.  It is such a nuisance! I also submitted feedback to Apple as well as Adobe.  Hopefully something is done about it.

I have this same issue, I’ll try the dock trick.  until now I’ve resorted to quitting LR and restarting. several issues with LR not managing macOS full screen mode correctly.

Does adobe monitor these threads? I was told by Adobe support that posting here was how we provide feedback to the devs regarding bugs etc.  But it seems like a community forum more than anything.

This is the best place to provide product feedback, feature requests, and bug reports.  Adobe senior support and product developers do actively monitor everything posted here, and they sometimes reply. 

Especially with intermittent bugs or bugs that only strike some configurations, it's important that everyone post here and click Me Too in the upper-right corner.  Adobe uses the number of Me Toos as one factor in prioritizing bugs. (Julian and Wayne, but sure to click Me Too.)

Iain, Julian, and Wayne: To enter full screen mode, are you clicking the green button, typing Shift + F, or doing the menu command Window > Screen Mode > Full Screen.  In the past, using the green button has confused LR.

The green button (this only happens on my MacBook Pro) has always seemed to me, as it is with other windows, the most direct and intuitive way. I think I've also tried the SHIFT+F method, and the display mode option, without success.

Try using Shift+F exclusively to enter full-screen mode and see if the bug happens. I can't find the "green button" bug report at the moment, but I vaguely recall it was reported fixed many versions ago. Perhaps it's come back with 10.14.

Using Shift F sort of works, but the advantage of using the max window button (aside from being intuitive and how we do it in every other Mac application that allows macOS full screen mode)  is it also moves Lightroom into it’s own space. If you manually put LR into a space and use this, things get very flakey and usually you can’t command tab from Lightroom to another app, and once you do you can’t keep the LR space active.  I’m a big fan of spaces and using several applications in full screen mode.  None of this is a huge deal, just seems odd that it’s been going on a long time and LR is the only application I use that seems to have trouble with Spaces and full screen mode.

I recall seeing other bug reports about LR not playing nice with spaces. It would certainly be better if LR could get it straightened out.  

To that end, if you can produce a precise step-by-step that shows how LR goes astray with the green button and/or with spaces, please post it as a new topic.  Adobe is much more likely to act on step-by-steps that demonstrate the bug for them.  (Not all the support people here are expert with LR.)  A screen recording is good, but if they can't easily reproduce the bug, then past experience shows they're less likely to escalate the bug to engineering.

I contacted Adobe and let them remote onto my system so that the agent could directly experience the problem. I also posted a video here as per Adobes suggestion. I am back on High Sierra due to this bug.

Unfortunately, the support representatives are of varying quality, and there's no assurance that they accurately report customer problems effectively.

That’s unfortunate. I removed Mojave and so cannot provide a more in depth video.

Guys can you all please click the ‘Me Too’ button at the top, as suggested by John? It may help Adobe pay attention to the problem.

Your video shows you are in "Apple" full screen mode.  Just click the 6th menu from the top to Exit Full Screen.  Unfortunately this is confusing as there are Lightroom Full Screen and Apple Full Screen modes and they are not connected.

Hi Robert, thanks for the response. If I go back to Mojave I will certainly test that. Perhaps one of the other users could test?

I will send myself a note to test this when I get home (I don't have my Mac at work), and I'll append to this thread a comment with the result.

Right, as previously recommended, try using Shift + F exclusively after restarting LR and avoid using the green button. That has helped others in the past to avoid these bugs.

Just to be clear, when LR is restarted, the drop down minimise menu works. When I say works, the minimise bar becomes visible. Without doing anything, this function ceases spontaneously, regardless of whether or not the green button is used.
To be able to exit, you can either quit LR or click Window and Exit Full screen. This reduces the screen in size so the minimise bar becomes visible again.
The minimise bar ceases to operate spontaneously, regardless of whether or not any of the buttons or shift F are used. I dont use full screen so have no need to toggle shift F, I need to minimise the application at times.

This reply was created from a merged topic originally titled Lightroom Classic: Full screen malfunction.

I have an issue with my MacBook Pro. When I first start Lightroon Classic 8.2.1 with Mojave 10.14.44, all is well and the minimise bar works correctly and, hovering the curser at the page top, brings down the menu with the minimise/maximise bar below.

After some editing, especially if I use menu functions such as undo, the menu drops down but the minimise bar then ceases to appear. The menu bar drops down and I can just make out the minimise bar brifely flashing - but it doesn stick around to be clicked on.

I can minimise the screen by selection of 'Window' and 'Exit full screen'. All works then works well for a while until the minimise drop down just ceases to work again - apparently spontaneously.

Also, I have noticed that if you try to import to the Library when the drop down isnt working, it is impossible to cancel the selection as tne canceland Import buttons on the lower right are not visible

Close full screen is a temporary solution but shouldnt be necessary

Please report back if using Shift + F exclusively, rather than the green button, works around this bug. That will help others and help Adobe narrow down the cause.

Shift F does not resolve the problem. Closing Full screen in the Window menu does. Close full screen this way and then you can maximise the screen again using the green button and then the missing bar works again - but only for a short time though.

I see no one has responded.  Shift F for full screen mode doesn’t work the same, as using the maximize button places Lightroom in it’s own full screen space which is how full screen works on the Mac.  Shift F takes over the screen and disables the ability to use the dock, and you can only use Lightroom reliably in Desktop 1 space, otherwise it simply flips back to space 1. So using this “exclusively” has it’s own problems which are worse than the current bug being discussed.

I guess I’m confused as to why LR isn’t just using the default OS full screen modes instead of apparently trying to roll their own.  Why not just allow users to utilize what the operating system provides like other applications out there and make sure it works?  Using alternative spaces is pretty standard now for many users, I have 6 or 7 apps running at a time, each in their own space, none with a menu bar. Seems LR should just be leveraging what the operating system offers.

Re LR and Mac spaces, please add your constructive opinion to this existing bug report, which Adobe has acknowledged and says is "in progress": https://feedback.photoshop.com/photoshop_family/topics/lightroom-always-switches-desktop-space-to-the-initial

Also, don't forget to click Me Too and Follow in the upper-right corner of that bug report. That will make it a little more likely Adobe will prioritize a fix, and you'll be notified when its status changes.

I think it's a bug in Lightroom Classic. If I understand you correctly, you're on Mac and referring to the red, yellow and green buttons on the upper left of each application's window pane that controls closing, minimising and maximising the window respectively. When you click on the green button, it maximises the window (i.e. displays the window in full screen mode in it's own space) and normally if you move the mouse to the top of the screen the Mac's taskbar (with application menu options File, Edit, etc.) and the window's title bar with the red/yellow/green buttons re-appear so you can click on the green button again to toggle full screen mode off and return the window to its original size (in its original space). Or you can press Control-Cmd-F to toggle full screen display off/on.

However, since I've upgraded to Mojave (10.14.5) and the latest version of LR recently (8.3.1) a few days ago I've noticed that when I maximise the LR window via the green button, Control-Cmd-F stops working and the title bar doesn't appear when I move the mouse to the top (Mojave's taskbar/menubar appears, but the window's title bar doesn't appear below it as it should). This only happens with LR, so I think it's a bug for Adobe to fix.

At the moment, my workaround is to quit LR and restart it. Then, instead of clicking on the green button to maximise the window by entering full screen, I just double-click on LR window's grey title bar: this causes the window to expand to cover your entire desktop (in the current space, so it covers any other open windows displayed on screen) but the title bar remains visible (so it's like full screen but with the Mac taskbar and window title bar still visible). I use Cmd-Tab to cycle through my open apps to display any hidden windows when needed.

I'm not seeing this bug in the current list of known issues for Lightroom Classic, though, so hopefully someone at Adobe registers this. Are any other Mac users experiencing this? If yes, what version of MacOS are you running? I did an in-place upgrade to Mojave (not a clean install), if that's relevant: worth knowing if the bug is also present on clean install. Also, I don't have Lightroom CC installed on Mojave: if anyone does have both Classic and CC installed, perhaps check if this same bug appears in LR CC (and report it in that category if it does)...

Iain, just discovered another solution. When you click on the green maximise button, it places LR in it's own desktop (or Space, in Mojave terminology). See the following for details: https://appleinsider.com/articles/18/10/12/how-to-use-spaces-apples-mostly-ignored-macos-mojave-prod...

If you press Control-Up Arrow (or Fn-F3) you'd get the Mission Control view showing any apps currently open as well as any Spaces at the top of the screen. One of those Spaces will have LR in it. You can just click and drag on the LR space to move the app from its Space back onto the main desktop space, and it'll revert to its normal position and size before you clicked on the green button (in effect, the same as if we were able to click on the green button to toggle maximise off).

Hope this helps...
