Lightroom Classic: Erratic Behavior When Using Multiple desktops

I did some digging around and came up with this about using Mission Control. Let me know if this helps...

1. Right click the Lightroom icon in the Dock and choose Options > None, like this:



2. Make sure the other open applications are set to None. (they should be by default)

3. Open System Preferences and choose Mission Control

4. Uncheck "Automatically rearrange Spaces based on most recent use" like this:



See if that makes the behavior stop. If not, go back and assign a Desktop to the Lightroom application. To do this:

1. Put Lightroom on an open Desktop 

2. Right click the Lightroom icon in the Dock and choose Options > This Desktop 

Let me know if that helps.

Hi Dave,

As a start you could try resetting preferences. Just hold down Alt / Shift (Win) or Option / Shift (Mac) while opening the app from the Creative Cloud desktop app then choose "Reset Preferences" 

Let me know if that helps.

Also, if that doesn't help, please share the version of your operating system and the version of Lightroom your are using.

Rick

Thanks, I  have reset preferences and will test it out, it is/was not consistent other than it only happens with certain combinations of apps running but LR was always one of them.

Dave

I have tried this and been running LR again today, it is still the same, LR flashes between screens and you have to not touch a mouse or keyboard until it settles and then hopefully you get back control, but not always first time.

Thanks Rick, I have been experimenting today and whilst the 1st of your suggestions was not relevant as this was the case for my settings anyhow, the second so far has worked. If you don't hear further assume all is well and thanks.

Dave

Good to hear, Dave. I'll bring this up with our engineers and try to suss out whether it's a Lightroom or Apple issue. 

Cheers!

This reply was created from a merged topic originally titled Lightroom Classic on Mac OS 10.13 - Going into Develop module flicks to new Deskt....

When I go into Lightroom and use shortcut D to go into the develop module the desktop changes away from Lightroom.  When I move into Library mode the same happens.  This has happened over several days and over several reboots.  

See Ricks reply, his second suggestion seems to be working for me!

1. Right click the Lightroom icon in the Dock and choose Options > None, like this:

I have this issue also and will try the work-around, but this isn't a fix as I do not have to do this workaround for any other application on Mac OS and changing a global setting in Mac OS for the sake of LR Classic CC indicates a bug to be resolved in LR.

This issue is still present in the most recent LR Classic CC (as of 5th May 2018).  It usually use this on my iMac which has a fixed multiple screen, however, currently i'm using LR on a MacBookPro with a temporary 2nd screen and have the same issue.  I'll lock LR to the 2nd screen as it has a higher resolution.

For me these are the issues I have on both my iMac and MacBookPro.

• Multiple screen setup.  The resolution of the screens do not match. 
• LR will spontaneously switch from one monitor to another.
• With multiple desktops, returning to LR will rapidly switch to another desktop.  e.g. if LR is on desktop 2 with Safari on desktop 1 (full screen), as perform the gesture to swipe to LR, LR instantly causes the desktop to switch back to Safari.  (I'm using Safari as an example, it can be any alternative desktop on the same monitor.)  As the original post mentions, you have to be extremely quick to catch LR and close it.  Sometimes I find hit F to switch the screen mode in LR resolved it. 

If there is any other information I can supply to help track the bug let me know.

I have this same issue. It has been plaguing me nearly a year now. I finally got so fed up with it today that I found this forum. Its pretty sucky that we have to lock lightroom to a certain desktop. It is definitely a lightroom issue because I have never had this problem with any other applications. It seems like lightroom just thinks it is locked to one of my desktops even though it is not. It is really annoying. I have it locked to a single desktop now but that means every time I use it I will have to lock it to whatever desktop I open it on which is just another step to remember. 

Same problem for me on a fresh install of Lightroom Classic (8.3.1 release). Main problem seems to be if you start Lightroom on one desktop and then move it to another the behavior gets all wonky.

Any way to reopen this bug?

Please reopen this and figure out what's wrong. Mark Whitelock's screenshot shows something interesting that I hadn't noticed before but can reproduce on my machine.

Happens to me from time to time. Very frustrating. 
I just checked and the window is also bigger like in Mark's screenshot, but it's bigger both in width and height

Still happening. Any plans to fix this?

The same problem here with LR 9.1
Very frustrating if using double monitors. Also happens if You start LR on one desktop and them move it to another. It randomly switches to old desktop leaving on on the new one. 

Pinning LR to one desktop does not help.
