P: Moving sliders causes image colors to dim and brighten

[RobStPete]

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.

[Victoria Bampton LR Queen]

Psychedelic colours are almost certainly the graphics card or driver.

[RobStPete]

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?

[Victoria Bampton LR Queen]

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

[RobStPete]

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.

[RobStPete]

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

[chriss57874268]

i had the same problem, i turned off Graphic Acceleration under Preferences  > Performance and it seemed to go away. Never had to do that before. for sure update.

Looks like this is related to that issue: https://feedback.photoshop.com/photoshop_family/topics/strange-behavior-when-movbing-vignette-slider...

[J453]

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:

[J453]

Thanks. Couple more questions:

1) when you stop moving the slider and let go of the mouse, does the image still look odd, or only when you're scrubbing?
2) If it still looks odd after you release the mouse, can we get a copy of the raw file and the sidecar with the settings that are looking wonky?

[RobStPete]

Sliders — Only when mouse is active. Ok on release. Also occurs when you click on the moving the image/recropping. This started after update was installed.

[SeraphStern]

And this one too : https://feedback.photoshop.com/photoshop_family/topics/lightroom-really-slow-artefacts-on-image-when...

[J453]

Hi Robert, we still haven't been able to repro. Sounds like getting a raw file with the sidecar with the settings for the file you're having trouble with might be helpful to our team to repro. Would you be able to post one (Creative Cloud/dropbox url, etc).

[RobStPete]

Wow! Wonder if this is an age factor. My mac is 2011. Will be back later and video the issue. FYI. This issue is not limited to RAW. It's also Tiff, PSD.

[RobStPete]

Interesting. I am working i n an older catalog I just updated and its not doing this. But was last night on a newer catalog. This catalog is 35 MB. Other catalogs range from 110 to 800MB

[chriss57874268]

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.

[RobStPete]

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

[RobStPete]

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.

[kpr-kom]

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...

[chriss57874268]

i would try to just switch off UGP. i have had no problems after that switch is off. going strong so far.

[kpr-kom]

you're right, I switched off UGP and it worked. Thanks Chris!

[tonysut]

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)

[bob50807878]

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.
