Lightroom 4.3: Rendering issues: pixelized image while making adjustments or brushing

Lightroom 4.3 final (on Windows 7 64bit, with an ATI Radeon HD5450, latest Catalyst 12.10 drivers) gives me some really weird rendering issues in the Develop module that were not present in the RC ("beta 6").

As long as I hover over the knob of a slider after making an adjustment, the image is not properly updated/refined and stays in an unrefined/pixelized state. This happens with ALL sliders in all sections of the Develop module. It was working in LR 4.2 and LR 4.3RC.

What's more, when I use the local adjustment brush, I see a MUCH larger area than the size of the brush affected initially as I add a brush stroke; only when I release the mouse button the adjustment is rendered correctly. Again, this too was working in LR 4.2 and LR 4.3RC.

Things I have tried: update/revert the graphics drivers (I tried a total of FOUR different driver versions). Update/revert the mouse driver. Delete the ACR cache. Start with a fresh catalog and no plugins, just adding something like 100 photos. Nothing helps.

To say the least, it is ANNOYING that something like the rendering in the Develop module is changed from an RC to a final version when it has such a MAJOR impact. It renders LR 4.3 final practically unusable for me; I've reverted to the 4.3 RC (which is faster and more responsive than 4.2 was).

I can see it too in 4.3, but not in 4.2.

Thank you for the confirmation Dorin. May I ask what system (OS, graphics card) you are using?

Also, I do not see these problems in ACR 7.3 with PS-CS6.

No problems here. Tried all ways to move a slider and they all work as expected. Same with the Adjustment Brush, no issues at all.

Also Win7 64bit, Ati HD5750 graphics card, though not updated to latest Catalyst version (still at 10.3).

Have you tried resetting the Preferences file?

Hi Jim, I'm aware that it doesn't affect all W7/64bit/ATI gfx constellations.

I tried resetting the preferences file but it didn't help either.

I suspect this is due to an optimization we added in 4.3 to keep rendering speed up while moving the sliders. Initially we draw from a smaller image size, then fill in with more detailed pixels once you've let go of that control. I had not heard of the issue with the local adjustment, however, and will ask one of our QEs to investigate.

Thank you Julie. I'd be all for such optimizations! If I can be of ANY further help tracking the problem down please let me know.

FWIW, no issue on OS X.

Paolo, how large in mpx are your files? Does your Fit view happen to fall between 1:4 and 1:2 or higher/lower?

This could well be a platform issue too, as this implies mouse tracking.

I wouldn't generalize it to "no issues on OS X" Paolo. It's great if 4.3 final works for you, but in the forum thread that I linked above there's one Mac user (reply #10) seeing problems with the adjustment brush as well.

Dorin, tried both on my MBP screen, where Fit view is smaller that 1:4 and my 27" LCD where Fit is between 1:4 and 1:2.

Alexander, I can't speak for anyone but me, it's pretty obvious. Sometimes, especially on the large external display, image refresh is very slow, but never frozen.
I suspect that a temporary slowness may be confused with the issue you described, at least on OS X. At least —FOR ME—.

I've noticed that the image display is temporarily incorrect when 'drawing out' a gradient with the gradient tool. Once the gradient end points are set it then redraws the image with the correct color. It's as it Lightroom doesn't use the display profile when drawing out the gradient tool. I've occasionally noticed with with the adjustment brush as well.

I've seen this is in LR 1-4 when using an external display on Mac OS versions 10.4-10.8. And FWIW, it's especially noticeable when connected to a projector.

This reply was created from a merged topic originally titled
Lightroom: Display incorrect during gradient creation.

I am finding that the render time for standard previews, from a Canon 5D MK2 raw file, has gone from 3-5 sec, to 15-20sec per file in this current version 4.3 of Lightroom. On an event with 2500 images, it now takes over 10 hours to render the standard previews.
My MacPro is new, 12 core 2.66GHz and has 48GB of ram.

Richard, my report is about rendering issues while in the develop module and applying both global and local edits to an image. The issues that I describe have nothing to do with preview rendering as far as I can tell.

I have the same problem here in LR 4.3. Sometimes the rendering is not finished and show a pixelated version of the picture. And, in some cases, after showing the not-finished picture, it gives me an "Unknown error" occurred.

LR 4.2 was much faster.

This is fixed for me in Lightroom 4.4 RC. Rendering speed while applying adjustments appears to have improved with it.

Just please don't change this between RC and final again. ;-)

Once again, Adobe screwed it up in the final! I can't believe this.

In 4.4 RC, changes are rendered fine when I adjust the sliders. In 4.4 final, I have to move the mouse AWAY from the slider for it to render the refined adjustments! It was FIXED in the RC, and it's BROKEN again in the final! Why are these functions being touched again when people report HERE that they are fixed in the RC?!?

I use LR 4.4 final

I remeber facing this problem, when using ONLY the external monitor. Is it the same same case for you?

I just unplugged and re-plugged the monitor it seems working. However this cannot be the solution.

However I don't remember the solution.
It could have benn related to monitor profiles, graphics card, color profiles etc.
Sorry don't remember.

What do you mean with "external monitor", Serkan? A secondary display? I am using a desktop computer and only have one monitor, connected via DVI.

Working on an image right now, and I'm having the problem again. One monitor. What a bunch of garbage!

Oooops, in this case it is something else.
In my case, Lightroom 4.4 have the above issues when I work with a Secondary Display; when I am on notebook PC there is no problem.
(It may have to do with the graphics card. It is Intel).

And:
Why does it write "SOLVED" for this topic on the top???

This is marked as solved because it WAS solved in 4.4 RC, but then reappeared in the final.

I don't think that anyone from Adobe is still paying attention to this topic.

Someone for adobe contacted me, I emailed them my files, XMP, made a video of it, etc. they can't reproduce it. Oh well, maybe when I pay to upgrade to version 5, they'll fix it.

So far my favorite version of lightroom was 3.6

I have to agree Noah... the whole 4.x series doesn't taste quite right. Too many bugs slipped through into release versions. Worse if it's bugs that were fixed in the RCs...

I'm test driving Capture One 7 Pro at the moment because of that, and I'm a Lightroom user since v1.x...

C17 sucks big time, crashes, crashes, crashes. I can't even import my whole library. I've tried aperture, it's just not quite there, photo ninja has potential, DxO is kinda neat, but I keep coming back to lightroom. They're close, but not great.
