P: Dialog for Export Settings gets trapped behind Photoshop windows

Same for me

I noticed that on my side disabling GPU support made things less laborious.
(Moreover, advanced tests have allowed me to see that the GPU was never solicited apart from the use of brushes, while slowing down everything else - usage advantage almost to zero all along)

Without the GPU it is more livable but, even downgrading the version of lightroom to the last but one can not reprofit with a proper speed thanks to the CPU + GPU

Please correct this defect, I spend hours on my photos ...

* Another problem appeared with the last 2 versions:
Full screen display bug on OSX latest version + iMac 5K.
as soon as we switch to another "desktop" or that we click elsewhere than in LR are display takes odd proportion until it becomes normal after a click in the app.


Courage and thank you to the develloppers for their work to make LR always more functional and powerful (a preference for me for the overall fluidity of the application, do not hesitate to load my GPU there is margin! ;))

Hi Philipp, same issues for me. Working on my photos has stopped - it's all problem-solving at the moment and has been for several months now.

I also did the re-install and made new smaller catalogs and all sorts of other little adjustments including the 7.4 update with no real improvement. My system is a new, fast iMac with 32gb ram and a SSD, which apparently well exceeds the minimum spec.

In my experience LR gets a bit erratic; sometimes takes 90 secs to change from Develop to Library module, if the program has been in the background. Showing/hiding masks may not work at all when clicking on edit pins and can take up to 90-100 seconds when selecting the checkbox. The brush lags so much that painting layers of adjustment is not functional.

It's become so frustrating I'm exploring migrating to other platforms to ease the pain! 

All very frustrating for a program that I use constantly and love enormously (when it works well!)

Hi Gretchen, I am having similar (same?) issues. Has your system improved with LRCC 7.4 release? Did you find any other solutions/improvements?

Cheers, Harvey

Same here, 7.3.1 didnt fixed any of the slow downs

It didn't solve any performance issue for me 😞

7.3.1 just came out a couple of hours ago. I'm not certain if it fixed this issue as I wasn't able to reproduce it, but you could give it a try to find out.

I wonder how long it will take them to make a patch...? This release was a total disaster, but I'm used to it by now.

I have the same problem:  I've upgraded Lr classic 7, and was looking forward to enjoying the new features. To my great disappointment Lr started working so slowly that I can hardly process my photos in it. It annoys a lot just to list presets, to say nothing to work in develop mode.
 How can I fix this problem? Can I upgrade it one more time? I'm afraid to reinstall Lr because I don't want to lose my albums, which I  had once in my practice..
