Lightroom Classic: Strange GPU Issues (artifacts) appear during edits in develop module

Hi All,

I need your collective help with an strange and frustrating issue.

Very suddenly last night after importing a batch of photos, I noticed that when trying to do some preliminary edits in Lightroom's develop module, a bunch of red/green/black/blue colored blocks would appear all over the image. See screen shot for reference.

At no time prior to last night did I ever encounter such an issue and for the last month or so I have been using Lightroom/Photoshop on a daily basis.

I checked that my Display driver was up to date (GeForce GTX 1050ti). it was not so I installed the updated version (445.87), however the issue persisted.

I decided to disable GPU acceleration to see if made any difference as the issue was limited to the Develop Module. It corrected the issue, however I don't consider this as a final solution, just a temporary work-around.

While creating the attached Screen Shot in Photoshop, I noticed that the same thing happens when in Photoshop. Unfortunately when disabling GPU support in Photoshop there is a noticeable performance decline, so again I would prefer not to have to resort to this quick fix.

I spoke to Adobe Support and they were massively unhelpful. 1 hour and a half online only to be told the my Graphics Card is not supported. Even though it is and has been working perfectly since 2018. After presenting this information to them they simply ignored any further chat communication.

Anyone got any ideas as to what could be the issue. Is it possible its a hardware fault that only happens during Lightroom/Photoshop usage?

Any help on the above would be appreciated.

All the best,

Patrick

P.S. The same post was made on the Lightroom community forum. I received many helpful suggestions however none of them worked.

Hey Patrick,
have you tried going backwards with GPU drivers yet? Maybe try one that is 1 or 2 months old or maybe even older just to test it out.
The fact it appeared over night in both applications makes it seem to me that one of the following caused it:

1. Windows updated something somewhere and it broke something once again. Did you notice any updates?

2. Some other software's auto updater did an update.

3. You updated or installed something that somehow interfers.

4. The GPU somehow partly died. Do you play any games by any chance so that you could see if the GPU performs as before?

5. Shot into the dark:
Go to services and right click the Nahimic service. Set it to disabled and then restart the PC and see if it helps.
Don't ask me why but this service is known to interfere with other software and it just enabled itself again on my workstation 2 or 3 days ago and caused Houdini to crash^^

I will see if I can come up with something else tomorrow.
Good luck!

Hi  Dziga,
Thanks for the suggestions.
I honestly have no idea if windows updated any thing, its totally possible as it always seems to be doing something!
I personally haven't installed or updated any thing recently.
I'm thinking that my GPU is dying and this is the 1st signs of it. However i cant seem to find any information to explain how to test it. The only thing I've done is to run a stress test using FurMark and it seems to perform totally fine. No issues with it or anything.
I don't play games at all so I'm unable to text it using any game.
I looked for the Nahimic service but couldn't find it installed on my PC, I seem to remember when i built the system I intentionally uninstalled it as it was known to cause issues with Adobe software.

If you happen to know of a good and reliable way to test my GPU i would be most grateful to hear it :)

Cheers,

P.

Mhhh, I am actually not quite sure.

The easiest GPU test is usually to put a different one into the system and test it. But that is not always the easiest choice, of course.

I don't know if there are any tests for the VRAM like there are for normal RAM (e.g. memtest).
Maybe you can search for memtest for GPUs and it will lead you somewhere useful.

To discover what services are running, use TaskManager and scroll down through the Services tab column.

To find out what Windows Updates have been made, go to Control Panel,then Windows Updates, and you will see where to discover all of the updates that have been done.

Statistically:
1) driver
2) the card fan has or is failing causing overheating
3) failing memory on the video card

Anyway to run test or diagnostic to confirm if it is any of the above?

Have this problem from time to time on all of my Macs. It is Adobe's problem. Lightroom has a massive problem with memory leaks, both on CPU RAM and also GPU RAM, Windows and macOS. 

In some past versions of LR (about an year ago) I even saw Safari tabs content rendered into exported JPG from LR. 

LRC runs the same speed on 2014 i3 iMac, 8GB RAM, 1080p screen as well as on 12-Core Mac Pro 2019, 64GB RAM, 5K screen. I can proof this.

It highly depends on what you are doing in LR and PS as a lot of tasks are just single threaded. Also, not to underestimate: the SSD/HDD when doing data intensive tasks in LR like exporting houndreds of files or PS' scratch disk. 

So yeah, I agree and disagree :D Both PS and LR could use major improvements on multithreading and caching and definitely seem way too slow on some straight forward tasks.
