Random color dots in develop module

[Guest]

I am hoping someone smarter than me can point me in the right direction here. I'm pretty sure I have a hardware issue, but I don't know what to troubleshoot. I have an issue with working with RAW images in Lightroom. I get a bunch of random colored dots everywhere throughout my image. I've uploaded two screenshots, the first is Lightroom in develop mode. The second is the same but zoomed into a discolored area.

I am running the latest version of Lightroom Classic CC version 7.0, just installed from Creative Cloud on a clean install of Windows 10. I am running a GTX 1060 graphics card with the latest drivers installed and 16GB of RAM.

The thing is the dots only appear about 50% of the time. As I am clicking through different images across the bottom, some images will have this effect, and others won't. When I reach an image that has the effect, I can often click on another image, then return to the problem one, and it will be fine. The effect carries over when I export to JPEG as well, and when I "edit in Photoshop". Additionally, I was having the same problem with the previous version of Lightroom but didn't try to troubleshoot because I was using another computer for photography.  It does this with both Sony and Canon RAW images and the RAW files all work perfectly fine on other computers, so this is a problem unique to this particular computer and not my cameras.

I have tried disabling the "Use Graphics Processor" setting, playing around with cache settings and the smart preview settings and nothing works. I have also tried different color management profiles in Windows.

Thanks for reading, I hope someone can point me in the right direction.

You've got the clipping indicators turned on (see How to adjust image tone and color, and work in grayscale in Lightroom Classic CC😞

To turn them off, do View > Show Clipping (see the menu for a shortcut), or click on the indicators.

The clipping triangles do not have white squares around them so the indicators are not turned on.  Also, isn't the clipping colors only blue and red.  I have never seen other colors.

Right, thanks, I should have looked more carefully.

Thanks for the response. Clipping indicators (View > Show Clipping) are turned off. No change. If was the clipping indicators, I would see the effect 100% of the time. But it only happens about 50% of the time. Click off an image, and back on sometimes fixes the problem. Additionally, if it was clipping indicators, I would not see the affect on the exported JPEG images. Here is a screenshot with the exported JPEG.

Upload the RAW and XMP or DNG file somewhere for others to try out.

Click here to download the file.

But it can't the raw file, since it happens randomly on hundreds of raw files from multiple cameras, and I can move all of my files to another computer and it works great.

Additionally this is a clean Lightroom install, so it can't be some setting I messed up. I also installed the new (non-classic) Lightroom CC and it does the same thing. There has to be some incompatibility with a specific component in my computer? But I don't know what component to replace or troubleshoot. All drivers are up to date.

This smells like a display profile issue:

- It occurs on exported JPEGs.  (What do those exported JPEGs look like on other computers)?

- It happens with GPU off.

- It happens in Photoshop.

- It doesn't occur on another computer.

After you export one of the problem JPEGs, view it on another computer -- does it show the problem?  If it doesn't, that more strongly indicates a profile problem. I recommend you try setting the display profile to sRGB, following the steps here: https://www.lightroomqueen.com/articles-page/how-do-i-change-my-monitor-profile-to-check-whether-its... . You said you tried that once already, but changing the color profile on Windows can be tricky, so it's worth double-checking following the Lightroom Queen's steps.

Yeah, I thought about the display profile, and I am still not ruling that out, but I did follow instructions to change the color profile, and it has no effect. Viewing the corrupted JPEG on another computer still shows the problem. I had to export 3 times, and the first two times the JPEG was fine, on the third try, the JPEG was corrupted, so like I said, it's not all the time. It's really strange.

Here is the corrupted JPEG.

Here is the XMP.

[johnrellis]

Definitely not the profile, then, since the JPEG is corrupted.

[Bob Somrak]

Its probably not the RAW file considering all you have said but we need to see your adjustments too.  Please upload and XMP file with your settings also.  It definitely looks like a graphics card problem but it is strange it does the same with and without the card enabled.  Strange problem for sure.

Did you ever solve this? mine does exactly the same thing. nothing to do with clipping as the effect appears randomly.

You’ve posted to an ancient thread. It is highly unlikely that the issue described in this thread, though not impossible, is the same one you are currently experiencing. Rather than resurrect an old thread that is seemingly similar, you are better off posting to a new thread with fresh, complete information, including system information, a complete description of the problem, and step-by-step instructions for reproduction. 

If the issue is the same, we will merge you back into the appropriate location. 

Thank you!
