P: Blackouts on secondary display in LR14.1

[Job56]

When editing an image in the Develop Module ie changing any of the sliders the image on the secondary display momentarily turns black. The primary display stays ok.

PC specifications:
LR 14.1 - Using Graphics Processor on Auto or Custom
W11 Pro - 23H2
Intel Core i7 12700 K - 32 GB RAM
GeForce RTX 3060 Ti - 8GB - with the latest drivers

[Job56]

When in the Develop Module and using the scroll wheel of the mouse with focus on the secondary display the info display on both displays alternates between on and off. 

PC specifications:
LR 14.1 - Using Graphics Processor on Auto or Custom
W11 Pro - 23H2
Intel Core i7 12700 K - 32 GB RAM
GeForce RTX 3060 Ti - 8GB - with the latest drivers

[AARDVARK7]

Same here. Completely different PC specs, so clearly a basic code error.

Do they not test these releases fully???

[Rikk Flohr: Photography]

I am unable to replicate this using the instructions provided.  Can you please post your exact video card model and the exact Graphics Driver version number?

[AARDVARK7]

As pointed out, the specifications for both machines are completely different, so your request suggests that you are looking in the wrong place for answers. The symptom is simple: when editing, the secondary display shows a black picture, rather than the correct image. The surround is still the same, so it is not a monitor problem.

[JohanElzenga]

Rikk does not say that it's a monitor problem, but because Lightroom Classic uses the GPU, it could be a GPU drivers issue. Outdated GPU drivers are probably the biggests cause of problems with Lightroom Classic on Windows computers. I do not see this on my Mac either.

[AARDVARK7]

I referred to the monitor just to provide more information. As to the drivers, I installed the latest on my PC last week and, as I mentioned, the two users reporting have entirely different set-ups: the OP uses Intel and GeForce whereas I have AMD CPU and GPU, so the likelihood of it being an outdated driver problem is almost nil.

[JohanElzenga]

Why are you so stubborn? If Rikk asks for this info, then just provide it. It may help to reproduce the problem, which is vital, because a problem that cannot be reproduced cannot be fixed either.

[AARDVARK7]

I'm not being stubborn, I'm merely reacting in the same manner I would had he asked me what brand of soap I use, or if my car has been serviced recently.

Even if I provided the information, the validity of it would depend on whether Rikk could assemble another machine exactly the same. It is the essence of scientific rigour.

Thank you. I've forwarded this information to the team. 

[Job56]

Thank you Rikk, 

I've reverted back to LR14.01 for the time being; no issues there.

Hope the team will find a solution. Thx again.

I was able to see both issues with my system.

1)  I opened a new image in Develop, clicked Auto and moved a few of the basic sliders around. No other Develop panels were used. (It occurs without using Auto as well)

The 2nd monitor screen blinks to black every so often as the sliders are adjusted sometimes getting stuck on a black screen.

It is inconsistent for which slider it affects and when it gets stuck.

It seems to settle down after Lightroom has been running for a while?

2)  If you move the mouse pointer onto 2nd screen and then rotate the mouse scroll wheel, then the Info display on both screens blinks on/off as it is rotated.  Unlike the screen blackout this is very repaetable, it is present every time you move the mouse scroll wheel while the pointer is on 2nd monitor.

I too am seeing intermittent blackouts of my secondary display. This occurs when I am in the Develop module on my primary display, with the secondary display showing Loupe in full screen. 

By "blackout", I mean the photo being edited is no longer visible on the display. However, all the other information in the UI for the display (e.g., header bar, loupe info overlay, bottom bar showing file name) all remain visible. 

When a blackout occurs, making any change to Develop settings (including any change to cropping) causes the image on the secondary display to re-appear. 

In some cases, I have been able to toggle the blackout on and off by making tiny adjustments to the position of one cropping line. In these cases, moving a cropping line a few pixels will end the blackout, and moving the cropping line back to its previous position will cause the blackout to recur. (I would provide a video screen capture of this behavior, but I haven't yet found a way to capture both screens simultaneously.)

Have the same problem ever since 14.1 version was released. 14.1.1 does not solve the issue. Graphics card is RTX3060, with driver update nov 2024. Windows 11, i9-14900k

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Ok, thankyou.(Hopefully there won't be many 'next times' - this is my first post as a user since 2007!)Sent from my Galaxy

[kglad]

no problem.

[warranted]

UPDATE
I rolled LrC back to 14.0.1 and the problem doesn't appear. 
Update again and it's back.

[Tony.S]

FWIW, this release of Lightroom crashes frequently on my system at seemingly random times. I've never had crashes before with Lightroom. 

[Job56]

Unfortunately the LRC 14.1.1 update hasn't resolved this; the issue still exists.

[AARDVARK7]

I suspect that this problem follows other performance issues, as I don't think that Adobe utilises current architecture properly. CPU cores, memory bandwidth, and GPU power all appear to be under-utilised, with inevitable glitches and hesitation during operation. 

It would be better if Adobe spent more time improving that side of the software, rather than developing the endless tools.
