LR4.1RC - Develop Module Blurring of image

Hi there, installed LR4.1 and the develop module has got worse. Every time I move a slider on any parameter the image goes blurry for about 5 seconds before returning to normal. This is especially noticeable when zoomed in

Most horrible to work with. What you've done please return it to the state of 4.0.

I'd rather have the dual monitor bug than this

Look like the sharpening is temporarily disabled while doing other adjustments.

I don't like it either. For me, it was fast enough with sharpening being adjusted in real time.

The most annoying thing is that the sharpening does not get rendered even if you let go the the slider (e.g Exposure) — I have to move the mouse off the slider.

I highly annoying. I like to move a slider to a position, observe the result and then re-move the slider to refine the setting.

this can't be intentional programming as it breaks all the rules of ergnomics

I haven't tried LR 4.1 RC yet but if the reported behaviour is intended then I add my vote to those arguing against it.

There must not be any distracting changes to the image, while one is varying an image parameter.

If PV 2012 is not efficient enough to support a proper user experience then it was not time to switch yet.

Thanks for the feedback. It is one of those things we're experimenting in improving the interactive performance of the LR dev sliders in 4.1RC. We see about 2x performance gain in some cases trying this trick.

The 5 secs delay is kind of excessive. It is not something we expected or experienced. I am wondering if this is related to the other known bug. Try hide the filmstrip and the second monitor display (if your setup has one). And see if the performance improves.

Do you normally see the same delay when dragging the sharpen slider?

It's a bit disconcerting that engineers are resorting to "tricks" to address performance issues in a product that's now in its 4th major release. The observed behavior does not occur when doing the same adjustments in ACR, and suggests that there may be some underlying problems in the LR implementation that might be contributing to the multitude of performance issues that are being reported.

That said, I agree with others that the behavior is very distracting and annoying when applying adjustments. As an experiment it should end up in the "fail" category.

Jim, "Trick" is a metaphor/figure of speech.

I hid the filmstrip and second monitor display and it made no difference.

You've made the interactive performance worse with 4.1RC. However I'm sure everyone appreciates the efforts to improve the develop module performance. it's historically always been slow for many many people even on extremely fast machines.

On a related note, I've found Disk access greatly affects performance and given it's a database based application I kind of understand.

unfortunately any performance gain under the hood is cancelled by the bad ergnomics and mental annoyances

Simon,
the reason why I have dismissed Bibble 5 (now available as AfterShot Pro) relatively quickly is that every time you change an image parameter, the image jumped around a little. I do not know whether this happens on all machines but it was so annoying that I stopped considering the software.

If LR 4 will continue to use such an annoying trick, I'll never upgrade. It is going to be LR 3.6 forever for me then.

I'd rather have the bad "Develop module previews do not feature noise reduction in some cases" situation back than annoying sudden changes before and after image edits.

Please consider giving users the option of turning this performance booster on or off. Ideally, give the user a choice of performance boosters, e.g.,
"no sharpening during adjustments": yes/no
"no noise reduction for low ISO images": yes/no

It is important that "no" is an option for any performance booster that has a visible impact on previews.

I completely agree, highly annoying, +1.

Especially that you have to move the mouse away from the slider to get the final rendering.

Interestingly, if you use hovering plus up/down keys, the same happens, but the final rendering appears after about 1 second. But not if you clicked on the slider before - than, the blurring does not go away until you move away the mouse cursor.

IMHO this makes the development module unusable and must have high priority to be fixed in the final.

Edit: Another "interestingly": The effect happens for all (?) sliders, with the following exceptions (as far as I could see): a) the point curve (*not* the region setting, only when moving the points directly), and b) the noise reduction. Note that the noise reduction itself is *not* temporarily switched off when moving e.g. exposure. So it seems to me that this behaviour is not intentional, but is in all likelihood a bug.

No, it's definitely on-purpose, as Simon posted above.

Downloaded 4.1 RC on my IMac, 8GB Ram, i7. Can now use "edit-in" function but when in the Library or Develop Module and switching to Print Module, picture does not render properly. It is blurry and appears out of focus. I have to switch back and forth between modules several times until image renders correctly. Note; the image in Library and/or develop module is tact sharp!
Adobe we all appreciate the teams efforts in correcting numerous issues with LR4 but 4.1 is still not right.
Tom, can we expect a real fix soon or do I abandon LR? (Rather not do).

I noticed another optimization: All local corrections (but not spot removal) are temporarily disabled when changing the amount of distortion correction in lens corrections -> profile corrections, and when changing any of the sliders in the manual transformation section.

This can be extremely annoying when adjusting perspective on a photo with strong local corrections. Try a strongly darkened sky using the graduated filter, and then change manual vertical transformation. When using hovering and up/down-keys for fine adjustement, the sky will turn bright and back to dark in intervals.

Yep... Lightroom 3 did that on the fly.

I can see that. It's interesting that it only happens with perspective control, but not with other adjustments. I just tried it. Well, it's odd and would be better the other way. But if that would mean that LR would be extremly slow again, I prefer to live with this odd behaviour (probably also because I usually do my perspective control before local adjustments.

To the sharpening issue: I can only see the effect when zoomed in 1:1. Since I don't do that often while moving sliders, it doesn't bug me at all - as opposed to the performance issues LR4.0 had, these were a dealbreaker for me.

But, I'm interested: Do you also only see this issue when zoomed in 1:1 or can you observe it even zoomed out? How strong do you sharpen your images? I have to admit I usually leave most of my images at my general sharpening preset and only sharpen more for selected photos.

Oh, and one thing: When I try to reproduce this behaviour, the image stays only unsharpened as long as I move the slider. As soon as I'm done, the image is sharp again. There is no delay of 5s on my machine or anything like that.

I'm having this same blurry issue when changing things in the develop module or using the brushes.

When I initially upgraded to LR4 I found the performance very slow - like others. But after a bit of internet searches for a fix I tried trashing the initial preference file that LR4 had created and allowed it to create a fresh one next time around.

Suddenly LR4 was quite speedy...!

I only tried 4.1 because I needed to bring my curve adjustments across accurately.

Now if I could get that speed that I had eventually got from LR4 with the curves maintained then I could be a much happier bunny.

The temporary deactivation of sharpening seems to be removed in LR 4.1 RC2.

The temporary deactivation of local corrections when changing the geometric lens corrections is still there - but I can live with that :-)

This is good news... I'll download it later and play.
