LightRoom 6: moving a develop slider results in temporary fuzziness

I've turned off graphics acceleration as it does not work on my machine (embedded Intel graphics only). I'm seeing some awful behavior in 6.0 versus 4.4 with every slider in the Basic panel of the develop module. Whenever I move a slider in 6.0, the image momentarily goes fuzzy, almost as if LR instantaneously turned clarity down to -40 or so. When I stop moving the slider, I then get the desired result and the image is crisp again. What's up with this fuzziness while I'm moving the slider? It causes great confusion while trying to make subtle changes. There's got to be some way to fix this.

That why there's a switch. It can cause more problems than it's worth if the graphics aren't up to the job.

What are the rest of your system specs? The blurring is a lower resolution version but it barely shows up if the graphics card is powerful enough.

Yes, but I turned the GPU option OFF and I still get the fuzziness. Is there anyway to get the old 4.4 behavior? I can live with the slower processing, but I don't think I can live with the flip to a lower resolution image every time I tweak a slider.

Here's the system info from LR. Any advice you can give is greatly appreciated.

One thing that seemed odd: The info below indicates (in the last line) that OpenGL is enabled. I would think that OpenGL would be disabled when the GPU is off.

That sounds stranger. With GPU off, behavior shouldn't have changed since LR5. Going back as far as LR4 though, I'm not so sure. I think we need an engineer on this thread.

Things should not change for the non-GPU render path. I am not able reproduce the issue from my end. Try restart Lr 6.

I not only tried to restart LR, but I also restarted my computer, and updated my intel display drivers. The problem persists.

And Lodimup below has the problem with a Nvidia GTX 970 card.

And on lightroomforums.net (where I originally posted this issue), user Clee01l (Cletus Lee) has also encountered the problem.

In one sense I'm glad to hear you can't reproduce it; I was afraid that this was the expected behavior. But please look into this until you can reproduce it and then find a fix for it. It is clearly occurring. 4 users have already confirmed it for you.

For me it puts on hold an otherwise easy "buy" decision.

Simon,

I've learned a bit more about this problem... if I am zoomed in at 1:1 or greater (2:1, 3:1 etc) there is no temporary fuzziness when I move a develop slider (highlights, for example). But if I am using anything less than 1:1, including "fit" and "fill," then the temporary fuzziness occurs every time.

As I said before, this is a huge problem while trying to tweak the settings on an image.

I am happy to discuss this with you further to help you reproduce the problem... as a former software program mgr I have a lot of experience in helping to reproduce defects. And, as I've said above, others are seeing this problem as well. I hope it can be fixed quickly.

Also, it only happens with the basic sliders. The sliders associated with the adjustment brush work fine.

I have this too, but only momentarily in zoomed 100%. It is quite annoying and strains the eyes.

This same problem was described by several users in 4.3 and 4.4 here:

The report says it was solved but if you read further on you find out that it wasn't.

Can't anyone help me with this?
