P: Image "blinks" when toggling between "Before Only" and "After Only" views in Develop module

I am afraid this in not fixed on my machine. There is an initial blink but when you toggle the switch again on the same photo, it doesn't happen. However, when I go to another photo and come back, it would happen again, initially. LR CC, Windows 10, Nvidia 1060(GPU on in LR), 32GB Ram, i7 3.4

As a workaround, try unchecking Preferences > Performance > Use Graphics Processor.

I have the same issue what Carl Scott 😞 it makes work really hard

Sorry to update again, but this actually does not seem to be fixed in the new release. It did seem that the behavior largely stopped after updating, but now it seems to be happening again, no differently than before.

I just installed Lightroom on a Windows 10 machine, and I am seeing my images get segmented (like it's dividing the image into 3-4 parts and putting a collage on the screen), every time I move a slider.  It goes back when I release the slider, but it makes it very difficult to edit!

System info below, hope a solution exists.

This appears to have been mostly fixed in 2015.10 with one small exception. There is still a blink / blip if one does like so:

1. Create virtual copy of image
2. Make some adjustment to image
3. In the History sidebar, select the previous state of the image ("Create Virtual Copy")
4. Then, in the History sidebar, select the following state (i.e. the adjustment that you made in step 2)
5. Press the "\" key to see the Before state (no blip / blink)
6. Press the "\" key again to return to the After state; There will be a blip / blink in transitioning back to the After state, but it seems to stop if one makes another adjustment, and then uses "\" to toggle the view again

I'm experiencing a similar issue on a 13" 2016 MacBook Pro, 16GB RAM, 500GB SSD, Intel Iris Graphics 550 1536 MB.

Intermittently, when entering crop mode, the photo goes black for a second or two. Not the entire interface, just the photo. 

Being that it is intermittent, it may take a tester a number of tries to replicate. I've noticed that when Lightroom's GPU is toggled off, the problem doesn't present itself. It appears only when GPU support is toggled on.

Extremely frustrating as just yesterday I purchased this upgrade to 6.10 because the 5.7 version ran  sluggishly on the new Mac. I bought it for its GPU support. Seems I've gone from bad to worse.

Please let me know if you need additional information.

lightroom 6 on iMac late 2012 3,4 GHz Intel Core i7 with NVIDIA GeForce GTX 680MX > when I hit \ to see the "before" view and the use of graphics processor is enabled, I get a flicker of the image. When I disable the use of graphics processor the flicker is not there and the transition between before and after is smooth. Annoying as we want to see subtle changes in a smooth way. Thanks for looking into it.
