Slow and or Application Hang in 4K Full Screen Develop Mode

[RP_LR]

Hi guys,

I have been struggling with Lightroom Classic since I upgraded my laptop to one with 4K-Monitor. It works okay but not amazingly fast in Develope Mode, but when I try to review and display the files in Full Screen, it just keeps hanging and crashing.

I run the subscription version of Lightroom up to date.

I have a Dell XPS 9500 (2020) with Intel I7 10. Gen (64-bit), 32GB RAM, Geforce GTX 1650 4GB. I mean, this is a really high-end PC, so the problem must lie somewhere else than in the hardware.

Could someone please help me out on this one?

Cheers 

Rui

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

We've reviewed the email address you use with this forum and find no crash reports in our system.

Did you see a crash dialog?

Do you use a different email address when filling out the crash report?

Was the crash dialog Adobe or Microsoft?

[RP_LR]

Hi Rick,

Well I didn't really get a crash report (maybe once or twice the message "the programm is not responding"), but often times it takes 30sec to load the Photo from Delevop into Full-Screen. 

I'd expect it to be faster

[RP_LR]

Hi Rick,

Do you have any idea what I could do to make it go away? Even today I was once agian trying to edit some photos and it took like 3min since I pressed F to full screen until the image showed up. The screen goes all black, it has a loading sign and hangs in there for 3 min until the image is displayed. And I don't do any other tasks simultaneously or have any other programs running.

It's just not normal and I have no idea why it keeps happening everytime I try to review in Full Screen.

Is your C drive (presumably where you have your catalog and images) a reasonably fast SSD drive?

[RP_LR]

It's a one year old top specced pc, so it's definetely ssd and I would suppose fast

[Jao vdL]

That's not it then. The behavior you describe sounds like the graphics card is not getting used. It's also weird your system info doesn't state the GPU is enabled for acceleration. What does it say in preferences for the GPU acceleration? Any difference when you disable it? Are you on the most up-to-date driver for the GPU (typically you need to get it from the manufacturer instead of Microsoft's update mechanism).

[RP_LR]

I am using the GPU for image processing (4GB dedicated GPU) and accelaration is enabled. Also the graphics are up to date. 

[Jao vdL]

Is there any difference when you turn the acceleration off? Faster/slower?

[RP_LR]

I don't really feel it makes a difference. 

I'm really getting sick of this PC-other programs incompatibility. My brother has a 8-year old Mac and it works smother than mine

So, after a long search in Google I actually found out what the problem (apparently)!

It was a colour profile issue with the Dell Monitor in the laptop. I changed the colour profile (ICC profile) from 14D0 to sRGB and it seems not to be hanging anymore.

Here's the thread to the solution, in case you sometime need to help someone else: https://community.adobe.com/t5/lightroom-classic-discussions/fullscreen-is-black-quot-before-quot-vi....

You're running LrC 10.4. Suggest updating using the Creative Cloud app to the latest 11.0.1 version and see if that helps.

[RP_LR]

I have currently already updated to version 11 from lightroom. Using Classic because I am more used to the layout.
