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.

Same problem for me,
on imac 27, with dual screen on display port

if i disable Gpu acceleration, no more problem

next update to correct this problem would be nice ;-)

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 was fixed in the CC 2015.1 / 6.1 Update.

Just updated to the new version and it still flickers the previous image while checking the before and after of the next image. Doesnt seem like it fixed.

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.
