Lightroom Classic: showing Red Previews and consuming Apple GPU resources

After updating to macOS Big Sur and the latest version of Lightroom CC Classic (10.2 release) last week I started having issues with Lightroom displaying solid RED previews in the library view. In short, I don't think it's a monitor, cable, or GPU issue, and rather a bug in Lightroom where over the course of 1/2 -1 hour Lightroom is maxing out my GPU memory. Switching Use Graphics Processor from Auto to Off and/or restarting Lightroom temporarily resolved the issue.

Once I see the RED previews, other things in my system (IG video stories in a chrome browser) also show RED previews. Is anyone else having issues like this?

This thread hasn't caught up? Red previews are fixed by upgrading to MacOS 11.5.

With the latest 10.2 version of Lightroom, sometimes image previews in the Library module will just be blank and completely red. The image is fine, I just have to switch to develop or sometimes zoom in. I've even tried regenerating 1:1 previews, but it keeps happening. I've never seen this happen before the latest update. It's not a huge issue but it is annoying when trying to quickly go through a series of images in the Library module.

What happens when you turn off your GPU (Preferences/Performance/Use Graphics Processor/Off)?

@carlos_cardona several have tried this and reported no change.   Sometimes the red appears then switches to the image, sometimes it’s the other order.   I gave a feeling this is an issue deep in the OS that's not going to be fixed by a simple flip of a switch.   So far, not one single person has offered the slightest explanation of what is actually causing this, so to me any of these guesses are basically time wasters.   I wonder if this happens if Big Sur is a new installation, not an upgrade … something not being cleaned up that is causing this problem.

My Big Sur installation is an upgrade, so I don't think that's relevant. It does kind of feel like it's a MacOS issue, don't ask me exactly why it's just a feeling, since changing the view from Grid to Develop and back sometimes fixes it, scrolling through them in Grid view, or a relaunch of LrC also fixes it. I wonder if Adobe has contacted Apple about this?

First, try disabling GPU in the preferences (Preformance). Any better?

If not, recalibrate and build a new ICC profile, the old one might be corrupted.

If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.

Thanks for the reply Andrew.

  1. I did try disabling GPU performance (switched from auto to off) did not resolve it without a restart of Lightroom. Again, it was fine, but only for 30 min to an hour before it started again. (I've had it on Auto for over a year on this computer and never had an issue.)
  2. I just have the basic standard apple calibration for my Dell Ultrasharp monitors. I recalibrated and created a new profile and deleted the original one for both monitors. Still having the same issue.

Thanks for the suggestions though!

@andrew_rodney I turned it off and waited. Here's a screenshot of how it shows in Lightroom when it happens. The crazy thing is that it seems to be hogging my graphics resources completely. I've attached a screenshot from Lightroom, and another from Instagram.

It does this on all image previews in Library and Develop?

@andrew_rodney No, it does it at random. If i go to the develop tab, i can see the image. It's so weird.

That it appears fine in Develop is a good sign. That module is unique in how it produces previews. I suspect all the other modules show this red as well? 

It sounds like maybe you should try rebuilding those previews. 

This article may help:

Optimizing the catalog can't hurt either but I think (hope) the above is the fix.

I am getting the same problem. On a 2019 iMac and latest Big Sur, and have tried the same fixes without success.

If I have Chrome open at the same time it will get the red blocks as well. But ONLY if I'm running LrC at the same time.

I can also get it on the preview pane of “get info” looking at random jpegs.   I’ll try shutting down LRC to see if it still happens elsewhere.  Today I got a giant oink square instead or red.

I am also seeing this same issue in Library - random images show all red on preview, switch to Develop and its fine? - 2019 Mac running latest Big Sur - just like all others here - anyone get an answer yet?

Adding a "me too" here. Started happening a couple of months ago, same things, random images in loupe view, just enough to be infuriating but not enough to be easily reproducible.  Worked with Apple and just got my logic board replaced (the issue was also showing up in Apple Photos, so it wasn't just LR) but after a complete reinstall and rebuild it happened again.  If I move from loupe to develop it will *sometime* go away, but I've also seen it in develop as well.  I did get rid of it by toggling the GPU acceleration off when I had it on the screen, but it seems transient so it's hard to tell.  It definitely has something to do with GPU and GPU acceleration though.

Another symptom that I'm wondering if anyone else has seen.  Sometime the LR app will stutter and all of a sudden there will be ghost windows showing through.  Like the dropshadow of windows behind the app that just the dropshadow is showing through the lightroom screen. 

I have a video of it shared here: https://www.dropbox.com/s/zkn7cu17n7r5y18/IMG_6323-1.mov?dl=0

In this case it's in Lightroom Desktop and triggered by doing an HDR merge, but I've seen it much worse and in LRC (just haven't been able to catch it).

I get the stuttering too in Classic when I get the red panels. I had it in the grid view in the Library module, very rapid, like the whole window vibrating.

It is intermittent though. It has also occurred in Chrome, which was open at the time it started in LrC. It's NEVER occurred when LrC wasn't in use.

A bit more info here.  I turned off the GPU acceleration, and when I went into a folder I had a lot of red squares.  When I viewed a photo via the space bar to go into loupe view, the image stayed red for a couple of seconds until it finished the 'loading..' and (I assume) a preview was created.

Normally the red squares are transient, but when I went back to grid mode they were still there.  I then selected all and did a generate of standard sized previews, and one by one they disappeared.

Maybe this *is* to do with currupt previews (in my case).  Maybe something in LR is trying to access bad preview data and is messing around with the mac video ... something?

I'm going to try by deleting the previews and starting again from scratch, as this obviously (?) isn't related to the LRC GPU settings.

(yes the app has been restarted since I turned off the GPU).

Ninja Edit: Just got it even with GPU off and working in a folder of brand newly generated 1:1 previews (with old previews file deleted).

@arcterex   I’ve seen variants of this, especially in Lightroom, BUT, it’s still the case that if I go into a folder of jpegs, entirely outside if LR, and hit the space bar to preview, those come up red (or pink).  Also, if you right click and do get info, the preview in the info pane is sometimes a red rectangle. 

And there are other LR issues … like a rapid thrumming between portrait and landscape, uncontrollable.  Sometimes I can switch to develop and stop it.   Awful!

I can't repeat the QuickLook problem on my Mac. Does this only occur when LrC is running?

@robgendreau At the time I was pretty sure it was a hardware issue so I didn't try quicklook or photos specifically with or without lightroom running.  It's very possible that it was always with LR running (it's running most of the time on this computer tbh).  The issue was more with Photos and LR than Quicklook, but seemed harder to reproduce with Photos vs LR.  Even with LR it's been far enough between it happening that it's not reproducible on demand.

@matt_temple I luckily haven't had the portrait/landscape thing happen, just the whole UI stuttering for a couple of seconds while that "background window ghosting" thing in the video I linked to happens.

I have facing the red screen problem on Ligthroom constantly. My computer has been updated and the GPU changed by Apple but the problem remains. My Lightroom Version 10.3, Camera Raw  13.3, MAC OS BIG SUR, version 11.4. My Graphics card is Radeon Pro 575X 4 GB. I've already turned of the GPU acceleration. Yes, I do experience the same behavior with the option to Use Graphics Processor disabled from Lightroom Classic. Is there anything that Adobe is being done to solve this issue? Also happens with Photoshop sometimes.

This seems to have something to do not only with LR and something to do with the OS generating previews somehow.  Just now with LR NOT open (but photoshop is) I opened an entry from Day One (mac journalling app) with 4 images in it.  Three were the red square, and then the images turned from red to normal images as (I assume) the OS downloaded the images from it's cloud storage or local storage.  Seems like it's something in the "turn a tiny thumbnail into a preview" function built into the OS somehow.

@arcterex I have exactly the same kind of issues.  (I’ve had a pink square a few times). The people at Apple you get when you report this issue are totally clueless.  Are they reading this discussion?   It’s a really horrible OS bug.

Really really really. … the same thing happens in finder previews using the space bar, in “get info” with jpegs, and using Preview.   And it only began to happen since I upgraded to Big Sur.   I agree that Adobe has an interest in figuring this out, but this is clearly not Adobe specific

I tried to repeat the Day One problem; couldn't. I had Ps or LrC running, but everything was OK in all three applications. But it seems to me that I only get issues once I've used LrC extensively for a while. And again, I've NEVER seen the problem with any other photo in any other application when LrC wasn't running.

@robgendreau The circumstances for the DO issue was it was a brand new install, I had opened it, logged into my account, and let it sit there for a day or so to let it download and sync (well, I also forgot about it and just left it open) and then opened up a couple of entries.  So it might have to do with the content being newly downloaded.  Not sure if you could simulate it by entering an entry with images on a different device, let it sync to the Mac and then open it up on the Mac.  It also wasn't *every* entry, just one or two of the bunch I went through.

Just to add to the commentary, I have been experiencing the same issue on my 2017 iMac, running Big Sur 11.4, 64gb ram, Radeon Pro 580 8Gb, using LR Classic 10.3, Camera Raw 13.3.

The issue is random and get red  previews in both Library and Develop modules. Have tried turning off the use graphic processor option but still had issues. One thing I have noticed is that it is more likely to occur after editing a large number of issue (50-100), although this is not always the case...just seems more frequent when doing this.

@KeithMulcahy My issue too seems to get worse the longer I have been editing. Hard to say for sure that's not just an illusion, but it definitely feels that way.

That's definitely my experience too.
