Lightroom CC/6: Annoying acceleration flicker glitch

Hi,

I just installed Lightroom 6 on my Windows 7 x64 machine.
It works just fine, however, after processing picture A (in the develop module) and switching to picture B (using the right arrow) if I click on "R" (crop) or "\" (compare to before) or zoom in, I see for a fraction of a second a flicker of the previously processed image A. (and I've already switched to image B)
FYI, I have an nVidia GTX 650 video card and process D810 raw files. Perhaps you're developing on super fast hardware and you don't notice it, but on my machine I do notice it all the time.
This doesn't occur when the graphics card acceleration is disabled, so this is clearly an acceleration bug. Also, it only happens when I have a secondary display enabled (I have a single card with dual DVI monitor support).

Very annoying!

While it causes no harm and it happens only the first time for each new picture I process, I find it very annoying. It's clearly a bug, because this shouldn't happen.

I can probably capture and post a video of this.

I am also seeing this flickering in Lightroom 6.0 when using the Before/After feature in the Develop module and "Use Graphics Processor" is enabled - the picture vanishes for a second and is then re-displayed. Turning "Use Graphics Processor" off makes the flickering go away.

This is on a Mac Pro (Mid-2012), Mac OS X 10.9.5, with "ATI Radeon HD 5770 OpenGL Engine" according to the performance tab of the Preferences.

Thanks.

Same problem with D600 files and Nvidia GTX750 Ti. But it appears only sometimes. (BTW, I find CPU processing faster on Corei7 4790K+16GB RAM+GTX750Ti+SSD than GPU accelerated. It is true that actual adjustments in GPU module are just a little bit more fluent with GPU acceleration, but image to image times are better with only CPU processing.)

Mine is flickering to black for a few milliseconds whenever I crop or close crop. Turning off GPU acceleration eliminates this issue.

I have windows 8.1 x64, gtx550 ti nvidia graphics.

Same problem (flicker when using \) even after the CC 2015.0.1 [1018753] update. Was able to work around it by disabling GPU acceleration.

Running on a 27" iMac, OS X 10.10.03, 4.0GHz CPU, 16GB Memory, AMD Radeon R9 M295X 4GB.

I can confirm that this flicker still occurs with the LR 6.0.1 update.
It occurs almost every time when the screen is refreshed (cropping using "R" or reviewing using "\", or when switching between photos using Left/Right arrows).

It may not be an issue for Adobe's developers, but for me (and apparently others) it's distracting and affects the fluency of my workflow.

I must admit that my NVidia card is reasonably powerful and can run many 3D games, however, I sense no noticeable benefit from having GPU enabled (compared to when using my i3770 CPU alone), so I have disabled it altogether with no apparent loss of functionality.

All in all, it feels like the product was rushed out without being completely polished, both in terms of bugs and set of useful features.

On another issue, some features I hoped they would add to this new release weren't added making this a rather "lukewarm" release, like having the spot removal tool support content-aware fill.
I would also allow to increase the compression range of shadow/highlight sliders. Improve the noise reduction tools, improve the "process" further (frankly, I prefer the Capture One process much better, however their interface and overall provided features are not as useful as lightroom, which is why I don't use it).

Same here. iMac, NVIDIA GeForce GTX 780M, 4 GB
The flickering is extremely distracting and makes it hard to judge subtle changes when toggling edited/original.

Fortunately the acceleration can just be disabled for now, so...not a big deal. But this was supposed to be the big new feature of LR6.

when in print module, the flickering is most annoying, with every mouse movement it flickers - switching off acceleration does not help

This is not fixed. Using the latest 2015.1.1 LR CC. If i use exposure, contact or any other sliders the screen flickers. It is very easy to reproduce. It causes terrible and quick eye fatigue.

Something is incompatible with your video drivers or video card or maybe the video card doesn't have enough memory to work with the size of images you're processing.

Try turning OFF the GPU support in LR / Prefs / Performance and see if things work better.

Tried it. Does not help. Only Adobe had this issue. All other apps are fine.

I recently did a full clean install of my operating system to windows 10 are re downloaded and installed lightroom, only importing my catalog. The issue still exists. When in develop module and you check the before and after of an image and then go to another image and do the same thing it will flicker the previous image first and then show the before of the image that is currently being viewed.The only way I have found to fix this issue is to disable the gpu acceleration. I have an nvidia card. Its a shame that the gpu has to be disabled as I do notice benefits in performance with regards to zooming and panning

I am the person who had originally started this thread and I'd like to respond to Rikk Flohr, saying that with the latest Lightroom 6.2.1 it still happens (it's very reproducible and occurs frequently)

Switching between photos in my catalog, the first time I click on "\" (compare before/after) or "r" (resize/rotate) I get a flicker showing the picture I edited previously. When disabling the video card acceleration it doesn't happen at all.

I am running Windows 7 Ultimate x64 with NVidia GT650 (using NVidias latest drivers).

Do you want me to record a video of my screen and post a link to it here?

The problem is most definitely not solved.
Maybe it's just a problem with me, but I must admit I've had too much disappointment with Lightroom lately. Buying Lightroom (rather than leasing it - aka cloud version) had placed me as a second-grade citizen, not enjoying the same improvements made to the otherwise identical cloud version, and some of the recent updates (like the new Import screen) are not to my liking. Top it with the bugs and issues with recent releases, some of which are simply not being addressed at all, and I'm left an unsatisfied customer.

I'll be honest with you, I've been experimenting recently with the Capture One 8.3's trial and I am quite impressed. I think I will wait for their next release and switch over. I just don't have the patience capacity to deal with Lightroom's issues right now. Sorry.

If you have any insights, suggestions or a timeline for a fix, I'd be glad to hear about it.

A video may help us isolate the issue. If you are willing to create one, I will forward it to the team.

FWIW. I am running the GT530 on Win 7 with no issues.

FWIW I just got the latest update a few days ago and I am now enjoying very pronounced flickering to black between images without doing compare or anything. Just switching images. I have Windows 10, AMD 8150 (8 core) with 24GB RAM, RAID 0 scratch disk, fast main library disk, a pair of GTX570 cards with Fremi. I was getting terrible lag and flickering and when I turned of GPU processing everything improved. This does not say much good about the code base.

Hi Rikk,

As you requested I have uploaded a video. Unfortunately I couldn't take a direct screen recording (it was too sluggish) and had to place a camera at front of the monitor, so please forgive the poor quality.

I was using Lightroom 6.2.1 on Windows 7 x64.
You can see the flickers (where you briefly see the previous image edited) while pressing the "\" (you can see the "Before" appearing just before the flicker) or when scaling using the "r". It's very predictable and completely reproducible as you can see from my repeated demonstrations.

From the list of people here, it is happening on Windows 7, 8.1, 10 and Mac OS X.
This is clearly not an isolated problem, however the reports here reflect people who:
1. Explicitly enabled the GPU acceleration.
2. Have bothered to report it.
3. Have found this specific forum/thread.

I am confident that this problem is far more widespread and may indicate some low level video buffer management issue.

Here is the link to the video: https://goo.gl/gX86up

Please keep us posted regarding this issue.

Martin and Tzi,

Just to confirm, you have the very latest drivers directly from the nVidia website? (Doing windows update won't give you the latest and greatest)

Hi, I have the same issue with the before and after flickering the previous issue when gpu acceleration is on. Would love to use the acceleration but this issue is just annoying. I have a gtx780 with the latest Nvidia drivers with Windows 10 and the latest update to lightroom.

That is correct, I always keep my drivers up to date. I have the latest nVidia drivers, just got an update last week.
According to the nVidia GeForce Experience tool I have drivers version 358.50 released on 10/07/2015.

And Windows update is up to date as well. If it helps, I am running on Intel 3770K with 16GB of RAM, my video card has 2GB of RAM.

Mind you, this has been happening since the release of 6.0 months ago, so this must have been evident during development/testing, so I doubt QA has missed it due to some update they have and I (and other people on this thread) don't. Especially since it has been happening on the latest and greatest Windows 10 and also on Mac OS X. (I wonder if it had the natively provided nVidia drivers by Apple, or installed the latest nVidia drivers from nVidia website)
