LIGHTROOM: Grain is totally wrongly rendered in Develop module!!

Hi,

This is a really really annoying bug. I hope Adobe correct that very soon because Grain was the reason for me to move from aperture to Lightroom!

I'm using 1920*1080 jpg images (frame captured from video) (but it seems i can have the same problem when i use bigger photos)
I'm editing them on a mac laptop (MPB), with a 1440*900 screen, in fullscreen mode, but with the editing column on the right side. So while i edit them, my images are about 1000pixels wide or a bit more. (It's fine for me since it's for being viewed on computers)

I apply a light grain but then i can't really see this grain in Library module or when i export the jpg... It appears that the Grain is actually rendered much more present in Develop Mode than in Library module. (When i zoom on the image to 100% then it's the same, but i don't want to edit my pictures in 100%...)

See crop of the images attached to this message: Develop Module on top, Library module bellow...

This bug is really annoying because all my NR/Grain fine ajusts on my pictures are wrong when i then export my pictures. So for now, the only workarounds are either to take 'screenshots' of my pictures while i'm in Develop Module using cmd-shift-4!! (This is what i'm doing at the moment, but then i would also have like to have them in bigger resolution) or i would have to switch continually to Library module while editing my photos....

Thanks,
Alexandre

This is actually not only concerning grain but also other develop settings: WHILE USING THE "FIT" OPTION IN THE NAVIGATOR, DEVELOP MODULE AND LIBRARY MODULE are rendering the image slightly DIFFERENTLY!

This is REALLY, REALLY, REALLY, REALLY annonying and it would be nice if someone from Adobe would answer.

Thank a lot.

Regards,
Alexandre

This just happen at the moment when i'm using a lot of sharpening (sharpening is at the maximum plus i'm using an ajustment brush over the whole image to increase again the sharpening)

Hi,
In the other forum, some people explain that this buggy rendering is a manifestation of "difference in scaling algorithm between Library and Develop." : because a jpeg preview would make the display (sometimes) unresponsive while dragging the sliders...

Since i have a lot of image of dance that i select from video shots, as frame, there are 1920*1080, and they wouldn't be that unresponsive. In some situations that happen a lot to me, the difference between the rendering in Develop and Library modules is REALLY HUGE. This is really confusing. The need to go back and forward between Develop and Library modules to edit the pictures is really anti-productive and anti-artistic in the workflow. At least it would be welcome to have either one of these options somewhere in the Lighroom preferences, or else, for the Develop Module rendering:

- toggle to switch to "jpeg preview", even if it's much slower, but at least we could look at the image at the same time treating it instead of being forced to go back and forward all the time to Library Module.

or/and

- toggle to switch to "updating to jpeg preview as soon as computed": While moving the sliders, the image would be first rendered with a "subsampling of the raw data" to react fast to the sliders, then a fraction of a second later the image would update to the "jpeg preview" as seen in Library!

I hope Adobe would take this in consideration. Today most of the time, photos are viewed on the web, in low resolution.

Sharpening Request:

Also It would be nice to have more sharpening than '150' and with bigger radius than '3.0', since i can't have a sharp enough image in the "jpeg preview" as in develop module. (it would prevent me from exporting in lower resolution, and re-importing in lightroom to sharpen again)

Other BUG happening in Library Module:

I get some low-res images that is not rendered correctly while i'm viewing 4000*6000 portrait images from my nikon D5200 in Library module, and while using the 'FILL' mode in the navigator (it's wrong only in this mode. 'FIT', 1:4, etc. are fine). The bug only happen with portrait oriented images. Landscape oriented images are fine. (Through it seems that it's not the only case where it happens...) MBPro i7 2011 - Mac os 10.8.5 - Lightroom 5.3 - having sidebars on both sides open in Lightroom.

Alexandre
