Image rendering not sharp when switching to Develop module.

[SiW]

Lightroom Version

13.0.1

Operating System

1. macOS 13 Ventura

Hi all

I use Lightroom Classic on my MacBook (M1) and have found that the image in the Develop module is not sharp in comparison to when it’s viewed in the Library module. It’s as if the Develop module image hasn’t rendered properly.

I believe this issue is a common one (?) and is solved by turning off LR’s use of the GPU.

This works and both images render correctly, but then when I move the sliders to make any adjustments in the Develop module, the image blurs slightly as the slider is moved and then sharpens up again when I stop the adjustment. Basically you can’t see the adjustments happen ‘live’.

Turning the use of the GPU back on fixes this issue but we’re then back to square one with the Develop module image not being sharp.
Is there a fix for this issue or is it a case of ‘live with it’ or buy a new laptop with a better GPU!

I don’t have these issues in Capture One, for what it’s worth. Perhaps C1 uses the GPU differently.

Thanks lots

Hello and sorry for all the updates. Had a free-ish day here so went deep on the testing!

The display is an external one. An Eizo ColorEdge CG223W. The laptop is closed. I guess the display is pretty old now... if that's relevant!

Another thing to try: Set System Settings > Displays > Color Profile to "sRGB IEC61966-2.1". Does the problem still occur?

LR sometimes has issues with specific third-party color profiles. though the issues are typically around colors or refusing to display an image at all. But it's a quick test. I think by default the Eizo ColorNavigator produces ICC v4 profiles, which in the past LR wasn't always happy about.

No change after trying that. The colour profile was produced on a SpyderXPro

Don't forget to change the profile back.

I tested the issue on this configuration and wasn't able to reproduce the problem:

- Macbook Pro (M1 Pro, 14", 2021, 16 GB)
- Mac OS 13.5.1
- LR 13.0.1,
- Eizo CG2700X running at "1600 x 900 (low resolution)" in Mac OS System Settings > Displays.

So somewhat different than your configuration: different version of the M1 chip, different version of Mac OS (with different graphics drivers), different display.

I tried large sample raws from these cameras, including the sample you provided:

I'm not able to update the laptop to Mac OS 14, which could potentially have different graphics drivers.

The thing that remains suspicious is that, even after forcing it to re-evaluate, LR thinks your computer doesn't support full acceleration, saying:

"Init State: GPU for Image Processing supported by default"

The M1 definitely supports full acceleration.

Possible next steps:

- Do you have Preferences > General > Use Smart Previews Instead Of Originals For Image Editing checked? That can sometimes cause issues.

- If you have access to another external display (e.g. a friend's), try that. Perhaps there's a bad interaction between the particular display, the GPU, and LR.

- Calling Adobe support about this is likely to be an exercise in frustration -- it's unlikely they'll have any more insight. With more complicated issues, they're hit or miss (more miss than hit). But if you're desperate...

- You could also post a bug report in the Adobe forums:
https://community.adobe.com/t5/ligh...-i-post-in-discussions-or-bugs/idi-p/13691887

That is very unlikely to lead to an immediate resolution, though it would be a place for others to add their "me toos" if it happens to them. Adobe won't pay any attention to it unless there is a recipe for easily reproducing it (which we don't have) or unless many others start reporting the same symptoms. As I mentioned before, if this were a general issue with some M1 laptops, we'd have seen a large number of reports on the forums by now.

Hi and thanks for taking the time to try and reproduce this issue. It was never going to be simple, unfortunately.

Yes, my plan is to try a different monitor, and a different laptop (M2) with my monitor & LR.

Will report back.

Did you see my last suggestion?

- Do you have Preferences > General > Use Smart Previews Instead Of Originals For Image Editing checked? That can sometimes cause issues.

Hi

Sorry. Yes. I tried this some time ago as one of the first potential solutions that came to mind.

I’ll let you know how the monitor test goes.

Today’s shoot was edited in Capture One!

Update.

I tested this issue with my laptop (and obvs my LR setup etc) on my friend's monitor. We were't able to reproduce the issue. LR still felt that the system only supported 'limited' acceleration, but there was no problem with any blurry image when switching between the two modules.

 

[johnrellis]

Very strange and unusual to see a bug dependent on the particulars of the display.

In the Adobe forums, someone recently reported very similar symptoms with an external display that went away after rolling back to LR 12 and then rolling forward to LR 13 again. Not at all clear it's the same underlying problem.

 

[SiW]

Gave this a test. No change. Thanks for the suggestion.

 

[SiW]

FYI. I tested this issue today with my friend's laptop (M2 Max) and my monitor and it reproduced itself exactly the same. So basically it's an issue between LRC and the monitor.

FWIW, LRC had set his GPU to full acceleration automatically.

Very strange indeed -- I don't recall seeing similar symptoms in all the years on these forums.
