Update to latest LR: Now, moving sliders causes image colors to dim and brighten in a psychedelic way!. Not good. Makes you think video card is going.

Psychedelic colours are almost certainly the graphics card or driver.

Only happens on image, no where else. tend to thing its the update. Had been using LR all night and then downloaded the update. Issue occurred only  after I downloaded and opened the update. Rest of the screen is fine. Other apps are fine. Only happens in LR.  Anyone else having this issue?

Yup, we've seen quite a number of people with psychedelic colours only on the image, usually fixed by a driver update.

OK, will check into that. Just happened after the update, so that is what makes LR suspect. Also happens when you crop your image and click to move around.

Curious though it only happened after the update. Also happens when you crop and move image around. will check into the driver.

Does this happen with all files or only specific ones?

It may help if we could see your Lightroom System Info with the Graphics Processor enabled (the state when you see the problem) Directions for sharing your system info from Lightroom:

found another solution that worked for me.

1. disabling "Use Graphic Processor" worked like a charm.
2. disable "UGP" and then uninstalled LR and reinstalled and then enable "Use Graphic Processor". I dont know if just uninstalling LR would work, just giving you my process.

This just started happening. The Catalog has been used for editing and restarted. The Catalog yesterday was 35MB. Now it's 230 GB.

What is not shown in the video is, the longer I hold down on the sliders, the more active the color change is on the dimming and brightness.

I made the same experience. Whenever I hovered over the sliders or I tried to drag them in any direction it dims and lightens and I also get a reduced quality of the image looking as it would have been painted with a fineliner...
I switched of graphics acceleration and LR runs like before the update. I now will follow Chris Schwegler in switching off the UGP having already uninstalled LR and am now re-downloading the app. Let's see what happens...  

No, does not help...

This reply was created from a merged topic originally titled Hardware acceleration playing up after update.

Lightroom updated a couple of days ago and now the screen flashes darker whenever I move a slider in develop module if graphics acceleration is turned on. Adobe really seem to have struggled with hardware acceleration implementation to me :( (using OSX El Capitan)

This reply was created from a merged topic originally titled Camera Raw / Lightroom - flicker in RAW.

Just updated to RAW 9.5 and Lightroom 6.5 and I'm experiencing the problem in both apps.

Whenever I make a change (exposure, contrast, highlights, blacks etc.) the image flickers. So there's no smooth transition, it just jumps around constantly from bright to dark and back again. It does end up with the correct result once I'm done but it's very difficult to see what I'm actually doing while doing it.

Macbook, El Capitan v. 10.11.4
All Creative Cloud apps are up to date

For future reference: Bo reported in the original topic that turning off the GPU in LR stopped the flickering.

I just downloaded 6.5 and am having terrible flickering problems.  Has anyone found a solution to this problem.  So upset - what a waste of money.

This reply was created from a merged topic originally titled Flicker issues with Camera Raw 9.5, Photoshop CC 2015 - Mac OS.

I'm running Adobe Photoshop CC 2015 in my 2011 21.5" iMac which is running OS X 10.11.3. After updating to the latest versions of both Photoshop and Camera Raw, ACR flickers my image from the current exposure to an extremely dark one then back to the current exposure. It's EXTREMELY annoying when trying to fine tune the look of an image.

SOLUTION PROVIDED BY ADOBE FOR MY PROBLEM:
I contacted Adobe's live chat and, after they took remote control of my computer and changed a few settings on Photoshop, the issue disappeared. The settings changed were:

Photoshop > Preferences > Performance > Graphics processor settings > Advanced:
"Use graphics processor to speed computing" tickbox: YES
"Use OpenCL" tickbox: NO
"Guides and ... edge sharpening" tickbox: NO
"30-bit display" tickbox: NO

Photoshop > Preferences > Camera Raw > Performance > "Use graphics processor" tickbox: NO

Changing these settings eliminated the issue for me. Hope it helps!

Our engineers have narrowed this down to an issue in the drivers for AMD cards on OS X. We're working with Apple to track down a fix.

The the meantime, the workaround is to disable "Use Graphics Processor" in Lightroom https://helpx.adobe.com/lightroom/kb/lightroom-gpu-faq.html#troubleshooting or Camera Raw https://helpx.adobe.com/photoshop/kb/acr-gpu-faq.html#Troubleshooting

Any update on this?
3 weeks seems adequate time to fix the problem - it is slowing my work down immensely with the graphics accelerator turned off and it is unusable with it turned on since the recentupdates

This turns out to be an AMD driver bug on Mac OS X 10.11. We're working with Apple/AMD to resolve the issue. For a workaround, turn off the GPU acceleration from the Preferences dialog.

Will you be advising us when the problem is solved.  Very annoying.

Turning off the acceleration is causing me major headaches as the system is considerably slower when editing images :(

And now it's already 1 month of struggling with this issue... Since Lightroom is almost unusable, I'm currently experiencing C1 Pro. Because, well, if we agree to all the burden of the monthly subscription system, we don't expect answers like "turn off this tech and get stuck with the old version".

Come on, guys,
even with a cooling dock, I've put an end to working without GPU acceleration, too much heating and noise from fans at max speed.

I am also suffering from this issue . Please fix this issue ASAP to not feel like I've done dumbest thing ever ; I've been using without any problem at all with LR4(downloaded illegally) until switched to CC . I should have donated 12$ to my hungry children in north part of my country ( I live in south Korea) .

OK, still not fixed after a month. I would like a FULL refund of this last month's money ASAP please. I am currently looking at another image processing solution and if this is not fixed soon, will stop paying you a load of money every month for faulty software.

It's a problem with a video driver not Adobe, so why aren't you threatening to switch to another hardware manufacturer for your video (or computer) and telling them they better fix it?

The point is , this issue never happened until adobe update is applied . 
Do you still think this is not problem of Adobe ? 
If Adobe cannot provide fix for this , or it takes much time , I think it is customer's right to use old version of product.  Why in the hell should I pay monthly for this  ?

Steve is correct. Unfortunately Apple and AMD are not responding. Adobe has tried to escalate the issue with them multiple times to the extent that we might need to blacklist the list of AMD GPU card that might be affected. You should push Apple and AMD if you can.

So now you have blacklisted my video card and LR is unusable and slow!!!!! Why kind of company are you ??? You screwed up, not AMD or anyone else. It all worked fine until Adobe updated LR. Not when AMD changed anything nor Apple changed anything, Adobe changed their software and broke LR!!!!!!!!!

Now fix it!!!!

Calm down my friend - When I applied below config.lua Simon suggested ,  my graphic card is not blacklisted any more and also original issue here we were discussing about seems to be gone . 
Is adobe working on tests before releasing stable fix ? Anyway currently I am happy with my lightroom . Hope this also works for you -  
For your reference , when I click "About This mac" ,

The following AMD GPUs on Macs running El Capitan are blacklisted in Lr 6.6 because of reported driver issue with El Capitan: Radeon HD: 6330M, 6350M, 6370M, 6430M, 6450M, 6470M, 6490M, 6530M, 6550M, 6570M, 6630M, 6650M, 6730M, 6750M, 6770M, 6830M, 6850M, 6850M, 6870M, 6950M, 6970M, 6990M.

It is reasonable for Lightroom to take the step to blacklist these AMD GPUs until the driver issue is confirmed fixed in an Mac OS X update (see note). If you are sure to take the risk for working with the non-officially supported GPU with Lightroom. Try the following,

  1. Open Lightroom.
  2. Invoke Lightroom > Preferences... menu command
  3. When the Preferences dialog appears, select the Presets tab.
  4. Click on the button labeled “Show Lightroom Presets Folder...”
  5. Lightroom will reveal the root preset folder in the Finder/Explorer.
  6. Now goto http://adobe.ly/29TzG8f  and download the config.lua file and copy it into the root preset folder at step 5. The config.lua setting would instruct Lightroom to bypass the blacklisting anyway.
  7. Relaunch Lr.


Hope this helps,



Note: Apple has informed us that the driver issue with these AMD card *may* have been fixed with the latest Mac OS X 10.11.5. So it would be good to get some confirmation from the folks who reported the issue here either with the Lr CC 2015.5.1/ 6.5.1 or with Lr CC 2015.6/6.6 following the documented workaround described above (with Mac OS X 10.11.5 of course).
