P: Rendering issues: pixelated 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).

    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. 😉

    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.

    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 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.

    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.

    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 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.

    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.
